An MCP server that tracks schema changes across the Microsoft Graph API — both the changes Microsoft documents and the ones it doesn't.
개요
An MCP server that tracks schema changes across the Microsoft Graph API — both the changes Microsoft documents and the ones it doesn't. Covers the full Entra ID, Entra ID Governance, Identity & Access Management, Entra Agent ID, and Information Protection surface, seeded with a year of history at launch. Ships with an interactive schema visualiser rendered inside the MCP client via MCP Apps. Microsoft Graph evolves continuously across v1.0 and beta. The official changelog is curated and incomplete — undocumented schema changes (new properties, removed relationships, new enum values) land in production before they're announced. This MCP closes that gap by diffing the actual $metadata CSDL daily, and backfills a year of history from both a public community tracker and the official changelog.

Microsoft Graph Atlas MCP
An MCP server that tracks schema changes across the Microsoft Graph API — both the changes Microsoft documents and the ones it doesn’t. Covers the full Entra ID, Entra ID Governance, Identity & Access Management, Entra Agent ID, and Information Protection surface, seeded with a year of history at launch. Ships with an interactive schema visualiser rendered inside the MCP client via MCP Apps.
Why
Microsoft Graph evolves continuously across v1.0 and beta. The official changelog is curated and incomplete — undocumented schema changes (new properties, removed relationships, new enum values) land in production before they’re announced. This MCP closes that gap by diffing the actual $metadata CSDL daily, and backfills a year of history from both a public community tracker and the official changelog.
Data sources
| Source | What it is | Granularity |
|---|---|---|
seed-entra-ms |
One-time import of changes.entra.ms’s historical CSDL diffs | Property-level |
backfill-graph-changelog |
One-time scrape of Microsoft’s official “What’s New” history, classified into 8 IAM object families | Feature-level |
self |
Daily $metadata fetch + diff, ongoing from first collection |
Property-level |
Two further tables enrich every change with real-world permission/role context: permissions (1,036 scopes scraped from Merill’s Graph Permissions Explorer) and roles (135 Entra built-in roles and their microsoft.directory/* actions, from the Microsoft Learn permissions reference), cross-referenced into role_permission_map.
Quick start (npx)
Requires Node.js 22+ (uses the built-in node:sqlite). Add to your MCP client — e.g.
Claude Desktop’s claude_desktop_config.json:
{
"mcpServers": {
"graph-atlas": {
"command": "npx",
"args": ["-y", "graph-atlas-mcp"]
}
}
}
That’s the whole setup: on first launch the server auto-downloads the latest published
database (change history, permissions, roles, embeddings) from this repo’s GitHub Releases
into ~/.graph-atlas-mcp/, and keeps it current against the daily release cadence.
Developing from source
git clone https://github.com/darrenjrobinson/graph-atlas-mcp.git
cd graph-atlas-mcp
npm install
npm run build
Populate the database (first run)
npm run seed # one-off: import changes.entra.ms's ~1,600 historical records
