IntuneRosetta-mcp

A Model Context Protocol (MCP) server that translates raw OMA-URI / CSP path strings into structured, human-readable Intune policy metadata — search 800+ pre-built policy records and resolve human-readable names to CSP keys, all from your AI assistant.

Quick start

No local installation required. Use npx to run the server on-demand:

npx github:UniverseCitiz3n/IntuneRosetta-mcp

Prerequisites: Node.js ≥ 18 and git available on your PATH environment variable.


Install in your MCP client

VS Code (GitHub Copilot)

Install with one click:

Platform VS Code VS Code Insiders
macOS / Linux Install in VS Code Install in VS Code Insiders
Windows Install in VS Code Install in VS Code Insiders

Or add manually to .vscode/mcp.json in your workspace (create the file if it doesn't exist):

{
  "servers": {
    "intunerosetta": {
      "type": "stdio",

    }
  }
}

    }
  }
}

GitHub Copilot Coding Agent (repository settings)

In your repository's Settings → Copilot → MCP servers, add:

{
  "mcpServers": {
    "intunerosetta": {
      "type": "local",
      "command": "npx",
      "args": ["-y", "github:UniverseCitiz3n/IntuneRosetta-mcp"],
      "tools": ["*"]
    }
  }
}

Available tools

Tool Input Description
translate_csp_key key (string) Translates a raw underscore-delimited OMA-URI / CSP path string into structured, human-readable policy metadata
batch_translate keys (string[]) Translates an array of CSP path strings in one call
search_policy query (string), limit (number, optional) Fuzzy keyword search across the policy database by name, description, category, or CSP path fragment
resolve_to_csp query (string), limit (number, optional) Resolves a human-readable policy name or keyword to matching CSP key(s) and full metadata
extract_and_translate text (string) Extracts all OMA-URI/CSP paths from a block of freeform text (Event Viewer XML, MDM diagnostic output, JSON exports, log files) and translates each one. Returns resolved policy metadata and a list of unrecognised paths
suggest_policy goal (string), context (string, optional), limit (number, optional) Given a plain-English security or configuration goal, returns matching CSP policies with recommended production values and reasoning
refresh_kb force (boolean, optional) Rebuilds the local KB by querying msgraph-kb with all predefined search terms. Requires MSGRAPH_KB_COMMAND to be set

Example usage

Translate a raw CSP key

translate_csp_key("device_vendor_msft_policy_config_defender_attacksurfacereductionrules_blockexecutionofpotentiallyobfuscatedscripts_2")

Returns:

{
  "name": "Block execution of potentially obfuscated scripts",
  "description": "This rule detects suspicious properties within an obfuscated script.",
  "value": "2",
  "csp_path": "./Device/Vendor/MSFT/Policy/Config/Defender/AttackSurfaceReductionRules",
  "category": "Defender ASR",
  "docs_url": "https://learn.microsoft.com/en-us/windows/security/threat-protection/microsoft-defender-atp/attack-surface-reduction"
}

Search for a policy by keyword

search_policy("bitlocker startup authentication")

Resolve a human-readable name to CSP key

resolve_to_csp("block obfuscated scripts")

msgraph-kb integration (optional)

IntuneRosetta can connect to the msgraph-kb MCP server to enrich its local knowledge base with live Microsoft Graph API metadata.

Set the following environment variables to enable this integration:

Variable Description Example
MSGRAPH_KB_COMMAND Executable used to launch the msgraph-kb server node or npx
MSGRAPH_KB_ARGS Space-separated arguments passed to the command /path/to/msgraph-kb/dist/index.js

When MSGRAPH_KB_COMMAND is set, IntuneRosetta automatically queries msgraph-kb in the background at startup and populates any missing records in the local database. You can also trigger a manual refresh at any time with the refresh_kb tool.

Example — VS Code with msgraph-kb integration:

{
  "servers": {
    "intunerosetta": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "github:UniverseCitiz3n/IntuneRosetta-mcp"],
      "env": {
        "MSGRAPH_KB_COMMAND": "npx",
        "MSGRAPH_KB_ARGS": "-y github:UniverseCitiz3n/msgraph-kb-mcp"
      }
    }
  }
}

Local development

Clone the repo, install dependencies, and build:

git clone https://github.com/UniverseCitiz3n/IntuneRosetta-mcp.git
cd IntuneRosetta-mcp
npm install
npm run build
node dist/index.js

Point any MCP client at the built binary:

{
  "mcpServers": {
    "intunerosetta": {
      "command": "node",
      "args": ["/absolute/path/to/IntuneRosetta-mcp/dist/index.js"]
    }
  }
}

Run tests:

npm test

How it works

At startup the server seeds an in-memory SQLite database from a pre-built knowledge base (db/intune-policies.json, 800+ records covering Windows, Linux, and Apple ADE) and applies a set of hand-curated seed records on top. Records include:

  • normalized_key — underscore-delimited CSP path (lowercase, device_vendor_msft_ prefix stripped)
  • name / description — human-readable label and explanation
  • csp_path — canonical OMA-URI path (e.g. ./Device/Vendor/MSFT/Policy/Config/Defender/AttackSurfaceReductionRules)
  • category — policy area (e.g. Defender ASR, BitLocker, LAPS)
  • docs_url — link to Microsoft documentation
  • value_map — map of raw integer values to human-readable labels (e.g. {"0":"Disabled","1":"Block","2":"Audit"})

When a translate_csp_key or search_policy call arrives, the server looks up the normalized key in SQLite, attaches the decoded value label, and returns structured PolicyMetadata.

If MSGRAPH_KB_COMMAND is configured, a background KB build queries the msgraph-kb MCP server with 20 predefined Intune-related search terms and upserts any new results into the local database — no manual curation required for Graph API endpoints.


Contributing to the DB

The pre-built knowledge base lives in db/intune-policies.json. If you know of a missing or incorrect policy record you can contribute it via a pull request — see db/CONTRIBUTING.md for full instructions, field definitions, and validation rules.

In short:

  1. Copy db/contribution-template.jsondb/contributions/<your-file>.json
  2. Fill in your records (required: normalized_key, name, csp_path, category)
  3. Run node scripts/validate-contributions.js locally to check for errors
  4. Open a PR — CI validates the file automatically
