Microsoft Teams MCP Server

MCP server for Microsoft Teams — search, message, and manage chats with browser-session auth; no Teams app approval or Azure AD registration.

Clone the repo, build it, point your AI tool at dist/index.js. Talks to the same Teams APIs the web app uses (Substrate, chatsvc, CSA). Auth is your normal Teams browser login; access matches what your account can already do.

Prerequisites

  • Node.js 18+

  • Microsoft account with Teams access

  • Chrome (macOS/Linux) or Edge (Windows)

Setup

git clone https://github.com/hickeroar/msteams-mcp.git
cd msteams-mcp
npm install
npm run build

Register it as a local stdio MCP server in whatever AI tool you use (Cursor, Claude Desktop, Claude Code, Augment, Windsurf, etc.). The shape is always the same: run node with the absolute path to dist/index.js.

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

Where that config lives depends on the client (examples):

Client

Typical config location

Cursor

~/.cursor/mcp.json (or project .cursor/mcp.json)

Claude Desktop

Claude → Settings → Developer → Edit Config (claude_desktop_config.json)

Claude Code

MCP settings / .mcp.json as documented for your version

Augment

Augment MCP / tools settings (add a local stdio server)

Exact UI labels vary; look for “MCP servers”, “Model Context Protocol”, or “custom tools”, then add a command + args (stdio) entry like above. Use an absolute path.

Restart or reload MCP/tools in that client after changing config or rebuilding.

First login

Ask the assistant (in Cursor, Claude, Augment, etc.) to call teams_login (soft {} first; use forceNew: true if the session is dead). A browser opens for Microsoft/SSO sign-in. Session files are saved under:

  • macOS/Linux: ~/.teams-mcp-server/

  • Windows: %APPDATA%\teams-mcp-server\

After that, tools use cached tokens. Tokens refresh automatically when possible; call teams_login again if auth fails.

After pulling code changes

npm install
npm run build

Then restart/reload the Teams MCP server in your AI client so it loads the new dist/.

Useful commands

npm run build        # compile to dist/
npm run typecheck    # tsc --noEmit
npm start            # run compiled MCP server (stdio)
npm run cli          # CLI with the same tools (no build required)
npm run cli -- status
npm run cli -- login
npm run cli -- find_channel --query "general"

The CLI shares the same session as the MCP server and is handy for debugging outside any AI client.
