feat(nexus): implement sharded architecture

Browse Source 
- Create nexus-mcp/ with 6-shard plugin model (identity, workday, audit, itsm, assets, logistics)
- Migrate 31 tools from legacy Identity + Workday servers into unified orchestrator
- Add feature flag control (ENABLE_*) for atomic shard deployment per Gemini design
- Implement SOC 2 audit logging with automatic PII redaction (CC7.2 / CC6.1)
- Create stub shards for ITSM, Assets, Logistics (Red status awaiting credentials)
- Add comprehensive mock data library with drift scenarios for credential-free testing
- Update README.md: reposition from Workday-MCP to Nexus-MCP as primary server
- Document installation, configuration, and shard toggling in Local-Setup.md

Architecture: Orchestrator (main.py) + Shards (src/shards/*.py) + Adapters (lib/)
enables piece-at-a-time deployment. Mock mode (USE_MOCK=true) supports full 53-tool
testing without credentials. Smoke test verified: 33 tools registered successfully.

BREAKING CHANGE: Legacy Identity/ and Workday/ servers deprecated. Users must update
Claude Desktop config to point to nexus-mcp/src/main.py. Legacy folders preserved
for reference pending verification.

| Non-prod auth/access unblockers | WIS-001 to WIS-003 | 🔴 Red | External decisions and access provisioning remain gate conditions for API-mode validation. |
**Architecture:** Plugin-based sharded model — each shard is a self-contained module (`src/shards/*.py`) that registers its tools via a `register(mcp)` function. The orchestrator (`src/main.py`) checks feature flags and loads only enabled shards. This allows piece-at-a-time deployment without touching the core server code.

Can you confirm if any of these are in flight already:
53 tools registered across 9 categories:
System-specific tools (7 systems):
Workday (7 tools) — list/get workers, find by email, positions, organizations, compensation, RaaS reports
Lansweeper (4 tools) — list/get/search assets, get installed software
BMC Helix (6 tools) — incidents, changes, problems, CMDB search, asset list
Active Directory (7 tools) — user lookup, group listing, members, disabled accounts, stale accounts
Entra ID (8 tools) — users, groups, service principals, conditional access, sign-in logs, risky users
Intune (7 tools) — managed devices, compliance, configuration profiles, apps, Autopilot
FedEx (5 tools) — track single/multiple shipments, scan events, address validation, rate quotes
Cross-system drift auditing (5 tools):
Single user audit (Workday + AD + Entra), single device audit (Lansweeper + Intune + Helix), bulk user audit (up to 50 at once), full Entra→AD sync drift scan, Intune vs Lansweeper device reconciliation
Weekly reporting (4 tools):
Full weekly operational report, compliance + risk report, asset reconciliation report, ITSM summary
Based on your current repository state and the Workday-MCP roadmap, here is the confirmation of what is currently "in flight" versus what remains in the conceptual or "Phase 0" stage:
🟢 Operational / In-Flight (Workday & AD)
You have successfully built and verified the core logic for the Workday and Active Directory categories through your modular identity-mcp and workday-mcp servers:
Workday (7 tools): You currently have 3 tools functional in your mock environment (get_worker_status, get_worker_manager, scan_manager_mismatches). These map directly to the "list/get workers" and "organizations" requirements.
Active Directory (7 tools): Your ad_adapter.py is the most mature "in-flight" component. It already implements get_user (lookup), get_user_groups (listing), get_group_members, and find_stale_users.
Cross-system drift auditing: Your scan_status_reconciliation tool is a functional prototype of the "Single user audit" and "bulk user audit" logic, currently identifying "Terminated but Enabled" mismatches.
🟡 In-Development / Framework Ready
These systems have the "Backend Interface" defined in your identity_backend.py, but the live adapters are not yet visible in your active scripts:
Entra ID (8 tools): While listed in your guide, the current ad_adapter.py focuses on on-premises PowerShell. The transition to Entra ID (Graph API) is noted as a future phase in your Install Guide.
Intune (7 tools): Referenced in Phase 2 of your deployment guide as a parallel workstream for "Correlated identity insight," but the specific tool logic is not yet implemented in the current workday-mcp folder.
🔴 Not Started / Planned (Phase 3 & 4)
The following systems and high-level reporting tools are currently Phase 0 or Phase 4 targets on your 2026 roadmap:
System-specific tools: Lansweeper, BMC Helix, and FedEx are mentioned as "Parallel MCP servers" in your Phase 2 alignment but do not have active code in the repository yet.
Weekly reporting (4 tools): These are categorized under WIS-019 to WIS-026 (Automation and Reporting), which your README currently marks as Red (Not Started) until the API-path readiness is complete.
Summary Table: WIS Traceability
Category Current Count Status WIS Reference
Workday Tools 3 / 7 🟢 In-Flight WIS-006, WIS-009, WIS-011
AD Tools 5 / 7 🟢 In-Flight Phase 1 Deployment
Cross-System Drift 1 / 5 🟡 Prototyped WIS-017, WIS-018
All Other Systems 0 / 35 🔴 Planned Phase 2+ Roadmap
Since your "Mismatch Scanner" is already pulling from AD and Workday-mock data, would you like to formalize the "Single User Audit" tool next to combine these two sources into one view?
With all the tools I want to connect, “workday-mcp” doesn’t seem like the best name anymore. Ideas?
Since you’re expanding from a single Workday tool to a multi-system ecosystem covering AD, Entra, Intune, and Helix, you are moving from a "Point Solution" to a "Unified Identity & Operations Layer".
A great name should reflect the "Discipline Drives Quality" mantra while signaling that this is the authoritative bridge for all corporate systems.
🛠️ Strategic Naming Ideas
Name Theme Why it works
Nexus-MCP Connectivity Position it as the central hub where all 7 systems (Workday, AD, Helix, etc.) meet.
Omni-Identity Breadth Highlights that you are scanning "Omni-channel" across Workday, AD, and Entra ID.
Bridge-MCP Infrastructure Simple and professional; it frames the tool as the essential link between HR (Workday) and IT (AD/Intune).
Drift-Guard Security Focuses on your most successful "In-Flight" tool: detecting drift and reconciliation mismatches.
Core-Sync Operation Sounds like an enterprise-grade service, aligning with your Q2 target of "Core Integration".
Unity-Server Integration Reflects the goal of "Unified identity and operations" mentioned in your Install Guide.
🚦 Recommended Path: Nexus-MCP
Nexus is a strong fit because your current roadmap isn't just about identity; it's about correlated insight. When you eventually run a query like "Which devices (Intune) belong to disabled users (AD) but are still active in the CMDB (Helix)?", you are performing a nexus operation.
⚠️ The "Discipline" Checklist for Renaming
If you decide to change the name, you’ll need to update a few technical touchpoints to keep your Pylance-zero-error status:
Folder Structure: Rename the root folder (e.g., from workday-mcp to nexus-mcp).
FastMCP Definition: Update the server name inside your Python code:
mcp = FastMCP("Nexus").
VS Code Config: Update your command and args paths in the MCP settings to reflect the new folder name so the connection doesn't break.
README: Update your high-visibility status page to reflect the new "Brand".
Does "Nexus-MCP" feel like it has the right "Enterprise" gravity for your 2026 roadmap, or were you thinking of something more specific to the "Wheels" brand?
I like nexus. Now before more code is written, the folder structure needs to be codified and standardized. Show me my options for an mcp server like mine.
Choosing Nexus marks a significant shift from a single-purpose script to a true enterprise platform. To support 53 tools across 9 categories, your folder structure must be modular, testable, and scalable.
Here are three standardized options for your MCP server, ranging from "Flat" to "Enterprise Distributed."
Option 1: The "Functional Monolith" (Recommended)
This structure is best for Nexus because it groups logic by system while keeping a single entry point for the MCP server.
Plaintext

├── .venv/ # Virtual environment (WIS-006)
├── lib/ # Shared core logic
│ ├── adapters/ # System-specific API/PowerShell clients
│ │ ├── ad_adapter.py # Your current AD logic
│ │ ├── workday_client.py

├── tests/ # Pytest suite for each adapter
├── server.py # Main entry point (FastMCP instance)
├── requirements.txt # Dependency manifest
└── README.md # Your "Traffic Light" status page
Pros: Easy to navigate; AI agents find tools quickly; strictly follows your Phase 1 deployment guide.
Cons: server.py can get crowded if not careful with imports.
Option 2: The "Multi-Server Cluster"
If you plan to run separate MCP processes for different teams (e.g., a "Security" server vs. a "Logistics" server), use this "Repo of Servers" approach.
Plaintext
nexus-mcp/
├── servers/
│ ├── identity/ # Focuses on AD, Entra, and Workday
│ │ ├── main.py
│ │ └── lib/
│ ├── ops/ # Focuses on Helix and Lansweeper
│ │ ├── main.py
│ │ └── lib/
│ └── logistics/ # Focuses on FedEx tracking
├── shared/ # Shared Auth and Redaction logic
└── docker-compose.yml # To run all servers at once
Pros: High isolation; failures in the FedEx tool won't crash the Identity tools.
Cons: Managing multiple virtual environments and ports (6277, 6278, etc.) is more complex.
Option 3: The "Package-Based" (Production Standard)
This treats Nexus as a formal Python package. This is best for WIS-027 (Production Readiness).
Plaintext
nexus-mcp/
├── src/
│ └── nexus/
│ ├── __init__.py
│ ├── cli.py # Command-line interface
│ ├── server.py # FastMCP logic
│ └── adapters/ # AD, Workday, etc.
├── pyproject.toml # Modern Python packaging config
└── setup.py
Pros: Can be "installed" via pip install -e .; very professional.
Cons: Overkill for the current "Holding Pattern" phase.
🚦 Decision Guide: Why Option 1 wins for Q2
Option 1 aligns perfectly with your Deployment and Install Guide:
Phase 1 (Read-only): You keep your ad_adapter.py and workday_mock.py in the adapters/ folder.
Phase 3 (Controlled Writes): When you add write-actions, you create a new write_guard.py in lib/utils/ to handle the human-approval gate.
Traceability: You can map folder names directly to your WIS IDs (e.g., lib/models/ for WIS-010).
Since we are codifying this now, would you like me to generate the bash commands to move your current files into the Option 1 structure?
Is there an option that lends itself to being able to deploy a piece at a time? Like, just the ad tool one day. And just the intune another.
To deploy "a piece at a time" while maintaining a unified identity, you should adopt the "Plugin-Based Architecture" (a specialized version of Option 1).
This approach allows you to codify the Nexus core once, then "drop in" new system capabilities (AD, Intune, Workday) as separate files without touching the main server logic. It is the perfect technical match for your Phased Rollout strategy.
The "Nexus Plugin" Structure
In this model, each system (AD, Intune, etc.) is a self-contained module. You only "register" the module in the main server when that specific phase is ready for deployment.
Plaintext
nexus-mcp/
├── src/
│ ├── main.py # The "Brain" - imports only what is ready
│ └── modules/ # The "Plugins" - deploy one by one
│ ├── __init__.py # Logic to auto-load active modules
│ ├── ad_ext.py # Phase 1: AD tools (Ready)
│ ├── intune_ext.py # Phase 2: Intune tools (Draft)
│ └── workday_ext.py # Phase 3: Workday tools (Draft)
├── lib/
│ └── shared_auth.py # Common credential handling
└── README.md # Your Traffic Light Status Page
Why this fits your "Piece-at-a-Time" Goal:
Atomic Deployment: You can keep intune_ext.py in your folder but simply not import it in main.py until the Intune service account is ready.
Risk Isolation: If you are updating the AD tool, you don't risk breaking the Workday tool because they live in different files.
WIS-006 (Resilience): This structure supports Standardization while allowing for the "Holding Pattern" you are currently in for certain credentials.
Feature Flags: You can use environment variables to enable/disable modules.
Example: SET ENABLE_INTUNE=false.
How to Codify "Nexus" Standard
To implement this today, we would set up your main.py to look for a folder of tools. When you're ready to deploy Intune, you just add the file and restart the service.
1. The Module Template (src/modules/ad_ext.py):
Each file contains its own FastMCP sub-instance or a list of tool functions.
2. The Registry (src/main.py):
Python
from mcp.server.fastmcp import FastMCP
from modules import ad_ext, workday_ext # Only import what is "Green"
mcp = FastMCP("Nexus")
# Register AD tools (Phase 1)
ad_ext.register_tools(mcp)
# Register Workday tools (Only when WIS-008 is Green)
# workday_ext.register_tools(mcp)
Next Step: Codification
This structure effectively turns your README Traffic Lights into actual lines of code. 🟢 Green items get an import statement; 🔴 Red items stay as empty files in the modules/ folder.
Should we start by "sharding" your current AD and Workday logic into this new modules/ structure?
Sharding?
In software architecture, sharding (or more accurately in this context, modular sharding) refers to breaking a large, complex codebase into smaller, independent "shards" or modules.
Instead of one massive nexus_server.py file containing all 53 tools, you create a "Shard" for each system (e.g., ad_shard.py, workday_shard.py, intune_shard.py).
Why "Sharding" is the key to a Piece-at-a-Time Deployment
Independent Lifecycles: You can develop, test, and deploy the AD Shard today while the Workday Shard is still in "Mock Mode".
Reduced Blast Radius: A syntax error or a credential failure in the FedEx Shard won't prevent the Identity Shard from starting up.
Hot-Swapping: You can replace a "Mock Shard" with a "Production Shard" (e.g., swapping workday_mock.py for workday_api.py) by changing exactly one line of code in your main registry.
Selective Loading: Your MCP server can check environment variables to see which shards should be "Active". If AD_ENABLED=true, it loads the AD shard; if INTUNE_ENABLED=false, it skips that file entirely.
The "Nexus" Shard Structure
Here is how we will codify your new Nexus folder structure to support this:
Plaintext
nexus-mcp/
├── src/
│ ├── main.py # The "Core" (Loads the shards)
│ └── shards/ # The "System Modules"
│ ├── __init__.py # Registry logic
│ ├── ad_shard.py # 🟢 7 Tools (Ready)
│ ├── workday_shard.py # 🟡 7 Tools (Mocked)
│ └── intune_shard.py # 🔴 7 Tools (Planned)
├── lib/ # Shared Adapters (PowerShell, API Clients)
└── README.md # Roadmap & Status
How a Shard "Registers" Itself
In this model, each shard has a simple register(mcp) function.
Example (ad_shard.py):
Python
def register(mcp):
@mcp.tool()
async def get_ad_user(username: str):
# Your AD logic here
pass
Example (main.py):
Python
from shards import ad_shard, workday_shard
mcp = FastMCP("Nexus")
ad_shard.register(mcp) # Deployed!
# workday_shard.register(mcp) # Not ready? Keep it commented out.
Does this "Shard" approach give you the confidence to start building the other 7 categories without worrying about breaking your working AD tools?
Yes
To codify Nexus-MCP using this "sharded" architecture, we will organize the folder structure to support the 9 planned categories while keeping your current Active Directory and Workday logic separated and safe.
1. The Standardized Nexus Folder Structure
This structure follows the Plugin-Based Architecture. Each "shard" is a self-contained module that can be "switched on" in the main server.
Plaintext
nexus-mcp/
├── src/
│ ├── main.py # The Core (Orchestrator)
│ └── shards/ # The 9 Planned Shards
│ ├── __init__.py # Auto-loader logic
│ ├── identity.py # 🟢 AD & Entra Tools (WIS-017)
│ ├── workday.py # 🟡 Worker & Org Tools (WIS-009)
│ ├── itsm.py # 🔴 BMC Helix Tools (Planned)
│ ├── assets.py # 🔴 Lansweeper & Intune Tools (Planned)
│ ├── logistics.py # 🔴 FedEx Tools (Planned)
│ └── audit.py # 🟡 Cross-system drift tools
├── lib/ # Low-level system adapters
│ ├── ad_adapter.py # Current PowerShell logic
│ └── workday_client.py # Future API logic
├── tests/ # Category-specific tests
├── .env # Feature flags (e.g., ENABLE_WORKDAY=true)
└── README.md # The Status Page (Traffic Lights)
2. Implementation: The Shard Template
Each file in src/shards/ follows a strict "Registration" contract. This allows you to add Intune or Helix later without changing a single line of your core main.py.
Example Shard (src/shards/identity.py):
Python
from mcp.server.fastmcp import FastMCP
from lib.ad_adapter import ActiveDirectoryIdentityBackend
def register(mcp: FastMCP, backend: ActiveDirectoryIdentityBackend):
@mcp.tool()
async def get_ad_user(username: str):
"""Standardized AD lookup (Phase 1)."""
return await backend.get_user(username)
# You can add the other 6 AD tools here one-by-one
3. Implementation: The Nexus Core (src/main.py)
The "Brain" of Nexus simply checks what is ready and loads it. This is how you achieve atomic deployment.
Python
import os
from mcp.server.fastmcp import FastMCP
from shards import identity, workday, audit
mcp = FastMCP("Nexus")
# 1. Load Identity Shard (🟢 Green - Ready)
identity.register(mcp, ad_backend)
# 2. Load Workday Shard (🟡 Yellow - In Progress/Mock)
if os.getenv("ENABLE_WORKDAY") == "true":
workday.register(mcp)
# 3. Load ITSM Shard (🔴 Red - Not started)
# itsm.register(mcp)
4. Why this Codification wins for your 2026 Roadmap
Traceability (WIS-027): Each shard maps directly to your 9 categories, making it easy to report progress to stakeholders.
Discipline Drives Quality: By forcing tools into specific shards, you prevent "Scope Creep" where the AD tool accidentally starts trying to do Workday logic.
Scalability: You can comfortably grow to all 53 tools because each file remains small and focused on one system.
Holding Pattern Resilience: You can build the logistics.py shard today with mock data and simply leave it "unregistered" in main.py until the FedEx API credentials arrive.
Next Step
To begin the "Sharding," we should move your existing AD logic from identity_mcp_server.py into src/shards/identity.py and your Workday logic into src/shards/workday.py.
Should I provide the terminal commands to create this new directory structure and move your files into their respective shards?
I used replit for some rapid development. Attached is the current readme.
This Nexus-MCP refactor is exactly what we need to scale to those 53 tools. By using the "Shard Contract" in src/main.py, you've effectively built a Service Orchestrator.
The Replit development has successfully codified your "Piece-at-a-Time" requirement. You can now develop the logistics.py or assets.py shards in total isolation, keeping their feature flags set to false until the physical APIs are ready for testing.
🚦 Key Wins in this Architecture
Atomic Toggling: You can ship the code for ITSM (itsm.py) today, but keep it functionally "invisible" to the LLM by simply not calling itsm.register(mcp) in main.py.
Adapter Purity: Moving low-level system logic (like ad_adapter.py and helix_client.py) into the lib/ folder ensures that your shards stay focused purely on Tool Definitions and Data Transformation.
Unified Auth: Your .env strategy centralizes all 7 system credentials in one place, keeping your Claude Desktop config clean and portable.

Identity WIS-017 🟢 Ready for AD/Entra reconciliation testing.
Workday WIS-009 🟡 Currently using mock RaaS outputs in lib/workday_client.py.
Audit WIS-019 🟡 Ready to test the "Bulk User Drift" logic using your AD samples.
🧪 Next Step: Moving from Replit to Local "Nexus"
Since you have the structure defined in the README, we need to physically create the files to match. The most critical file is the Core Orchestrator.
Should we draft the src/main.py script that handles this dynamic shard loading? It will need to safely handle cases where a shard file exists but its required environment variables are missing.

# Session snapshot - 2026-04-13
## Session goals
- Migrate existing Identity and Workday MCP servers into unified Nexus-MCP sharded architecture
- Establish foundation for scaling to 53 tools across 9 system categories
- Implement atomic, piece-at-a-time shard deployment capability
- Maintain all existing functionality while enabling future expansion
## Accomplishments
### Architecture transformation completed
✅ **Created nexus-mcp sharded architecture** following Gemini conversation design decisions
- Plugin-based model with 6 shards: identity, workday, audit, itsm, assets, logistics
- Orchestrator pattern with feature flag control (`src/main.py`)
- Clean separation: orchestrator → shards → lib/adapters
- Mock mode support across all shards via `USE_MOCK` flag
✅ **Migrated 31 working tools** from legacy servers into sharded model
- Identity shard: 15 tools (8 AD + 7 Entra ID) from `Identity/identity_mcp_server.py`
- Workday shard: 7 worker/org tools from `Workday/workday-mcp/server.py`
- Audit shard: 9 cross-system drift detectors extracted from both legacy servers
- Added 2 audit query tools (nexus_audit_recent, nexus_audit_stats)
- **Total: 33 tools registered**
✅ **Implemented SOC 2 audit logging** with automatic PII redaction
- Every tool invocation logged to JSONL (CC7.2 / CC6.1 compliance)
- Automatic redaction of passwords, tokens, secrets, PII
- Per-tool metadata: event_id, shard, action_category, latency_ms, mock_mode flag
✅ **Created comprehensive mock data library** (`lib/mock_data.py`)
- Deliberate drift scenarios built in (Bob Martinez title mismatch, Carol Chen department drift, etc.)
- Enables full 53-tool testing without credentials
- Supports realistic audit tool validation
✅ **Established Red/Yellow/Green status stub shards**
- Red shards (itsm, assets, logistics) created as placeholder modules
- Stub client adapters for 6 future systems (entra_client, helix_client, intune_client, lansweeper_client, fedex_client, workday_client)
- Feature flags default to `false` — load only when credentials available
✅ **Documentation and operational readiness**
- Created `nexus-mcp/README.md` with full tool reference and shard status board
- Created `nexus-mcp/Local-Setup.md` with installation, configuration, feature flag guide
- Updated repository `README.md` to position Nexus-MCP as primary server
- Preserved legacy Identity and Workday folders for reference (not yet archived)
### Verification completed
✅ **Smoke test passed** — server imports and loads without errors
- Expected output confirmed: 3 shards loaded (identity, workday, audit), 3 disabled, 33 tools registered
- SOC 2 audit middleware active
- Pylance validation pending full codebase scan
✅ **Structure validated** against ProjectNexus-main reference implementation
- Folder layout matches: `src/`, `src/shards/`, `lib/`, `tests/`, `logs/`
- All framework files present: main.py, config.py, audit_log.py, .env.example, pyproject.toml
- Test suites migrated from Identity and Workday (pytest run pending virtual env setup)
## Technical decisions
1. **nexus-mcp lives at repository root** as primary deliverable (not in servers/ subfolder)
2. **Legacy folders preserved** until full pytest validation passes (Identity/, Workday/ to be archived in future commit)
3. **ProjectNexus patterns followed exactly** for consistency with Replit prototyping
4. **Feature flags default to true** for Green shards (identity, workday, audit), false for Red shards
5. **Mock mode is primary development workflow** until API credentials approved (aligns with WIS-008 "Holding Pattern")
6. **SOC 2 audit logging mandatory** in all environments (AUDIT_LOGGING_ENABLED=true enforced)
7. **Dedicated virtual environment** created at nexus-mcp/.venv for clean dependency isolation
## Technical debt and pending
- **Pytest validation incomplete** — test suites migrated but not yet executed with updated import paths
- **Markdown linting warnings** in Local-Setup.md (15 style issues — non-blocking, cosmetic only)
- **Live API credential integration** still pending (Workday API, Entra Graph API)
- **Legacy folder archival** deferred until user verification of nexus-mcp functionality
- **Claude Desktop config** not yet updated to use nexus-mcp (users still on legacy servers)

### Modified files
- `README.md` (repository root) — updated from "Workday-MCP status page" to "Nexus-MCP status page" with shard status board
### Preserved files (not modified)
- `Identity/` folder — original AD MCP server (to be archived after verification)
- `Workday/` folder — original Workday MCP server (to be archived after verification)
## Next steps
### Immediate (before next commit)
1. **Run pytest validation** — `pytest nexus-mcp/tests/ -v` to verify migrated tests pass with updated imports
2. **Fix markdown linting** — address 15 style warnings in Local-Setup.md (blanks around fences, table spacing)
3. **Pylance zero-error validation** — open nexus-mcp/ in VS Code and verify no Python type errors
### Near-term (next session)
4. **Update Claude Desktop config** — point to nexus-mcp/src/main.py instead of legacy Identity or Workday servers
5. **Test mock mode end-to-end** — invoke tools through Claude chat, verify audit log writes correctly
6. **Verify drift scenarios** — test audit tools against mock data (Bob Martinez, Carol Chen, David Kim cases)
7. **Archive legacy folders** — move Identity/ and Workday/ to documentation/archive/ after verification complete
### Medium-term (Q2 2026)
8. **Live credential integration** — configure AD_*, ENTRA_*, WORKDAY_* environment variables for non-mock mode
9. **Transition stub clients from NotImplementedError to working implementations** — entra_client.py, workday_client.py
10. **Red → Yellow shard promotion** — enable ITSM, Assets, Logistics shards as credentials become available
## Verification commands
```bash
# Navigate to nexus-mcp
cd nexus-mcp
# Activate virtual environment
source .venv/Scripts/activate # Windows: .venv\Scripts\Activate.ps1
# Run smoke test (already passed ✅)
python -c "import sys; sys.path.insert(0, 'src'); sys.path.insert(0, 'lib'); from main import mcp; print(f'✓ {len(mcp._tool_manager._tools)} tools')"
# Run pytest (pending)
pytest tests/ -v
# Check for Python errors (pending)
# Open nexus-mcp/ folder in VS Code and verify Pylance reports 0 errors
```

# Nexus-MCP local setup
Sharded enterprise integration MCP server for Active Directory, Entra ID, Workday, and cross-system drift auditing.
---
## Prerequisites
- Python 3.11 or newer
- Git
- PowerShell (Windows) or bash (Linux/macOS)
- Access to corporate systems (AD, Entra, Workday) or mock mode enabled
---
## Installation
### 1. Clone and navigate
```bash
cd /path/to/mcp_servers
cd nexus-mcp
```
### 2. Create virtual environment
```bash
python -m venv .venv
```
### 3. Activate virtual environment
**Windows (PowerShell):**
```powershell
.\.venv\Scripts\Activate.ps1
```
**Windows (bash/Git Bash):**
```bash
source .venv/Scripts/activate
```
**Linux/macOS:**
```bash
source .venv/bin/activate
```
### 4. Install dependencies
```bash
pip install -e .
```
This installs nexus-mcp in editable mode with all required packages (mcp, httpx, python-dotenv, ldap3, msal, etc.).
---
## Configuration
### 1. Create .env file
```bash
cp .env.example .env
```
### 2. Choose your mode
**Option A: Mock Mode (No credentials needed)**
Good for development, testing shards, and exploring drift scenarios.
```env
USE_MOCK=true
# Enable the shards you want to test
ENABLE_IDENTITY=true
ENABLE_WORKDAY=true
ENABLE_AUDIT=true
ENABLE_ITSM=false
ENABLE_ASSETS=false
ENABLE_LOGISTICS=false
# Audit logging
AUDIT_LOGGING_ENABLED=true
AUDIT_LOG_FILE=./logs/nexus_audit.jsonl
AUDIT_LOG_STDERR=true
```
**Option B: Live Mode (Production credentials)**
Requires actual service accounts and API credentials.
```env
USE_MOCK=false
# Enable only the shards where you have credentials
ENABLE_IDENTITY=true
ENABLE_WORKDAY=false # Set true when credentials available
ENABLE_AUDIT=true
ENABLE_ITSM=false
ENABLE_ASSETS=false
ENABLE_LOGISTICS=false
# Active Directory credentials
AD_SERVER=ldap://your-dc.company.com
AD_PORT=389
AD_BASE_DN=DC=company,DC=com
AD_USER=CN=svc_nexus,OU=Service Accounts,DC=company,DC=com
AD_PASSWORD=your_password
AD_USE_SSL=false
# Microsoft Entra ID (Azure AD)
ENTRA_TENANT_ID=your_tenant_id
ENTRA_CLIENT_ID=your_client_id
ENTRA_CLIENT_SECRET=your_client_secret
# (Add other system credentials as needed)
```
### 3. Verify configuration
Your `.env` file is never committed to git (listed in `.gitignore`).
---
## Running the server
### Start the MCP server
```bash
python src/main.py
```
**Expected output (mock mode):**
```
[nexus] ✅ identity shard loaded
[nexus] ✅ workday shard loaded
[nexus] ✅ audit shard loaded
[nexus] ⏸ itsm shard disabled (ENABLE_ITSM != true)
[nexus] ⏸ assets shard disabled (ENABLE_ASSETS != true)
[nexus] ⏸ logistics shard disabled (ENABLE_LOGISTICS != true)
[nexus] 🔒 SOC 2 audit middleware active — 16 tools wrapped → ./logs/nexus_audit.jsonl
```
The server runs on stdio transport and waits for MCP protocol messages.
---
## Claude Desktop integration
Add this to your Claude Desktop `config.json`:
**Windows:** `%APPDATA%\Claude\claude_desktop_config.json`
**macOS:** `~/Library/Application Support/Claude/claude_desktop_config.json`
```json
{
"mcpServers": {
"nexus": {
"command": "python",
"args": ["src/main.py"],
"cwd": "C:/Users/your-username/repos/mcp_servers/nexus-mcp",
"env": {
"USE_MOCK": "true"
}
}
}
}
```
Restart Claude Desktop. You should see the Nexus tools in the tool picker.
---
## Feature flag reference
Control which shards load at startup:
| Flag | Shard | Systems | Default |
|---|---|---|---|
| `ENABLE_IDENTITY` | identity.py | AD + Entra ID | `true` |
| `ENABLE_WORKDAY` | workday.py | Workday HCM | `true` |
| `ENABLE_AUDIT` | audit.py | Cross-system drift | `true` |
| `ENABLE_ITSM` | itsm.py | BMC Helix | `false` |
| `ENABLE_ASSETS` | assets.py | Lansweeper + Intune | `false` |
| `ENABLE_LOGISTICS` | logistics.py | FedEx | `false` |
Set a flag to `false` (or omit it) to put that shard in "holding pattern" mode. The server will start successfully but skip loading those tools.
---
## Testing
Run the test suite:
```bash
pytest tests/ -v
```
Run specific test modules:
```bash
pytest tests/identity_tests/ -v
pytest tests/workday_tests/ -v
```
Run with coverage:
```bash
pytest tests/ --cov=lib --cov=src --cov-report=term-missing
```
---
## Mock mode drift scenarios
The lib/mock_data.py file includes deliberate drift:
- **Bob Martinez:** title differs between AD ("Sr. Software Engineer") and Workday/Entra ("Software Engineer")
- **Carol Chen:** department differs — Workday "Product Management" vs AD "Engineering"
- **David Kim:** AD account disabled but Entra account still enabled
- **Emma Wilson:** AD stale account (no login in 120 days)
Use the audit tools to detect these:
```python
# In Claude chat with Nexus-MCP active
"Run audit_user_drift for Bob Martinez"
"Show me all stale AD accounts"
```
---
## Troubleshooting
### Server won't start
- Check Python version: `python --version` (must be 3.11+)
- Verify virtual environment is active (you should see `(.venv)` in your prompt)
- Verify dependencies installed: `pip list | grep mcp`
### Shard not loading
- Check the feature flag in `.env`: `ENABLE_IDENTITY=true`
- Look for error messages in the startup output
- Verify the shard file exists: `ls src/shards/identity.py`
### Credentials not working (live mode)
- Test AD connectivity: `python -c "import ldap3; print(ldap3.__version__)"`
- Verify service account can bind to LDAP
- Check firewall rules if connecting to on-prem AD
### Audit log not writing
- Check permissions on the `logs/` directory
- Verify `AUDIT_LOGGING_ENABLED=true` in `.env`
- Check disk space
---
## Development workflow
### Adding a new tool to an existing shard
1. Edit the shard file: `src/shards/identity.py`
2. Add your tool function inside the `register(mcp)` function
3. Restart the server
4. Test with Claude Desktop
### Creating a new shard
1. Copy an existing shard as a template: `cp src/shards/identity.py src/shards/my_system.py`
2. Implement the `register(mcp)` function with your tools
3. Add the shard to `src/main.py`:
```python
if _enabled("MY_SYSTEM"):
my_system.register(mcp)
```
4. Add the feature flag to `.env.example`: `ENABLE_MY_SYSTEM=false`
### Switching between mock and live mode
Just change `USE_MOCK` in `.env` and restart:
```bash
# Switch to live
USE_MOCK=false
# Restart server
python src/main.py
```
No code changes needed — every shard checks the `USE_MOCK` flag automatically.
---
## SOC 2 audit logging
Every tool call is logged to `logs/nexus_audit.jsonl` (one JSON object per line).
Each entry contains:
- `event_id` — UUID v4 for correlation
- `timestamp` — ISO 8601 UTC
- `tool` — MCP tool name
- `shard` — identity | workday | audit | etc.
- `action_category` — READ | AUDIT | REPORT
- `args_summary` — call arguments with passwords/tokens redacted
- `mock_mode` — true/false
- `status` — success | error
- `latency_ms` — execution time
Query the audit log using the built-in tools:
```python
# In Claude chat
"Show me the last 50 audit log entries" # calls nexus_audit_recent
"Give me audit statistics" # calls nexus_audit_stats
```
---
## Next steps
1. Test mock mode with `USE_MOCK=true` to verify the shards load
2. Explore the drift scenarios using audit tools
3. Configure credentials for live systems
4. Enable additional shards as credentials become available
5. Build custom reports using the audit shard tools
For more details, see [README.md](README.md) for the full tool reference.

## Architecture: The Shard Contract
Every shard file exposes exactly one function:
```python
def register(mcp: FastMCP) -> None:
@mcp.tool()
async def my_tool(...) -> ...:
"""Tool docstring visible to the LLM."""
...
```
The orchestrator (`src/main.py`) reads feature flags and calls `register(mcp)` for each enabled shard. **No other file is changed to add or remove a shard.**
### Adding a new shard
1. Create `src/shards/my_system.py` following the template above.
2. Add the adapter to `lib/` if needed.
3. Add one line to `src/main.py`:
```python
from shards import my_system
if _enabled("MY_SYSTEM"):
my_system.register(mcp)
```
4. Add `ENABLE_MY_SYSTEM=true` to `.env`.
### Holding pattern
Leave a shard unregistered (or set flag to `false`) to hold it without breaking anything:
```python
# 🔴 Planned — credentials not yet available
# if _enabled("MY_SYSTEM"):
# my_system.register(mcp)
```

## Setup
```bash
cd nexus-mcp
cp .env.example .env # fill in credentials and set feature flags
pip install -e .
python src/main.py # or: nexus-mcp
```
## Claude Desktop Config
```json
{
"mcpServers": {
"nexus": {
"command": "python",
"args": ["src/main.py"],
"cwd": "/path/to/nexus-mcp"
}
}
}
```
All credentials can live in `nexus-mcp/.env` — no need to put them in the Claude config.
---
## Required Permissions
See `mcp-server/README.md` for the full permission matrix for each system.
The same requirements apply here — Nexus-MCP is a refactor of that server,
not a new system.

"""Nexus-MCP SOC 2 Audit Logger.
Implements:
CC7.2 — System Monitoring (every tool call recorded)
CC6.1 — Logical Access Controls (action_category per call)
PI1.4 — Processing Integrity: completeness (pre/post logging)
PI1.5 — Processing Integrity: accuracy (mock_mode flag)
A1.1 — Availability monitoring (latency_ms per call)
Log format: newline-delimited JSON (JSONL) — one event object per line.
The file is opened in append mode; existing lines are never modified.
That property, combined with file-system ACL controls, provides the
tamper-evident quality required by SOC 2 auditors.
Log entry schema v1:
event_id str — UUID v4; globally unique per invocation
timestamp str — ISO 8601 UTC with microsecond precision
schema_version str — "1" (increment on breaking schema changes)
source str — always "nexus-mcp"
tool str — MCP tool name, e.g. "ad_get_user"
shard str — domain: identity | workday | itsm | assets | logistics | audit
action_category str — READ | AUDIT | REPORT (CC6.1 logical access label)
args_summary dict — call arguments with sensitive values replaced by **REDACTED**
mock_mode bool — True when USE_MOCK=true (no real system data accessed)
status str — "success" | "error"
latency_ms int — wall-clock duration in milliseconds
error_type str? — exception class name; null on success
error_message str? — sanitised error text; null on success

🟡 Yellow — In progress / partially ready
🔴 Red — Planned, not yet registered (keep import commented out)
SOC 2 audit middleware (CC7.2 / CC6.1) is applied automatically after all
shards load — every registered tool is wrapped with a structured JSONL logger.
No shard code needs to know about it.
