EntraID MCP Server (Microsoft Graph FastMCP)

The EntraID MCP Server is a modular, resource‑oriented FastMCP implementation that exposes Microsoft Graph API capabilities to AI assistants. It solves the common pain point of integrating Azure AD/EntraID data into conversational agents by providing a single, well‑structured endpoint that can be queried for user information, group membership, application registrations, sign‑in logs, MFA status, and more. Developers can use this server to let AI assistants perform real‑time identity operations without writing custom Graph calls or managing authentication flows themselves.

The server’s architecture centers on a centralized Graph client that handles token acquisition and request signing, ensuring consistent authentication across all resources. Each resource—users, groups, applications, service principals, sign‑in logs, MFA status, and password management—is implemented in its own module under . This modularity makes it straightforward to add new capabilities, such as device or role assignment management, without touching the core server logic. The FastMCP framework automatically registers these resources as tools and prompts, allowing an AI assistant to invoke them with simple JSON payloads.

Key capabilities include:

• User operations: search by name or email, retrieve a user by ID, list privileged directory role members, and fetch all roles assigned to a specific user.
• Group lifecycle management: create, read, update, delete groups; add or remove members and owners; search for groups and list their memberships.
• Application & service principal management: list, create, update, delete app registrations and service principals; view role assignments and delegated permissions for each.
• Sign‑in log querying: fetch recent sign‑in events for a user, supporting audit and compliance scenarios.
• MFA status checks: determine MFA enforcement for individual users or entire groups, aiding security posture assessments.
• Password reset: generate secure passwords or accept custom values, optionally forcing a change on next sign‑in.
• Permissions helper: automatically suggest the minimal Microsoft Graph permissions required for a requested operation, helping developers implement least‑privilege access.

These features make the server invaluable in real‑world workflows such as automated onboarding, compliance reporting, security incident response, and identity governance. An AI assistant can, for example, answer a user’s request to “reset my password” by invoking the tool, or provide an executive with a quick view of all privileged users by calling . Because the server adheres to FastMCP’s context‑based error handling and logging, developers can debug interactions effortlessly while the assistant remains responsive.

The MCP server integrates seamlessly into existing AI pipelines: it can be deployed behind an API gateway, connected to a chatbot platform like Claude or OpenAI’s agents, and leveraged in CI/CD scripts that manage Azure AD resources. Its extensible design means teams can evolve the server as new Graph endpoints are released, ensuring that AI assistants stay up‑to‑date with the latest identity features without requiring frequent code rewrites.
