What is the Ms MCP server?

Ms MCP server is a hosted integration for AI assistants that speak the Model Context Protocol. Microsoft SharePoint MCP server.

What you get

Calendar · Contacts · OneDrive · Outlook · SharePoint — on the official @modelcontextprotocol/sdk, over stdio or Streamable HTTP.

What the assistant can call

Once Ms is connected, these are the calls the assistant has available:

  • stdio — for local MCP clients that launch the server as a subprocess (Claude Desktop, IDEs, the MCP Inspector)
  • Variable — Used by
  • MICROSOFT_CLIENT_ID — stdio
  • MICROSOFT_TENANT_ID — stdio
  • MICROSOFT_ACCESS_TOKEN — stdio
  • MICROSOFT_MCP_CACHE_DIR — stdio
  • MCP_TRANSPORT — both
  • PORT — http
  • MCP_HTTP_BODY_LIMIT — http
  • MCP_DEBUG — both

Configuration and credentials

You will need 3 environment variables: MICROSOFT_CLIENT_ID, MICROSOFT_TENANT_ID, MICROSOFT_ACCESS_TOKEN. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

  • Node.js >= 20 - pnpm 10 (corepack enable)

Setting it up

Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.

Choosing this one

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Ms's toolset — stdio, Variable, MICROSOFT_CLIENT_ID and 7 more — is a fair guide to whether it matches your workflow. It is maintained by ko1ebayev; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Before you rely on it

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • With 10 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Ms.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the ms mcp server does with a few real requests.

Frequently asked questions

It connects Ms to MCP-compatible AI assistants such as Claude and Cursor, exposing 10 tools (stdio, Variable, MICROSOFT_CLIENT_ID, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Ms directly.
