What is the Microsoft 365 Teams MCP server?

Microsoft 365 Teams MCP server exists for a simple reason — assistants are far more useful when they can act on Microsoft 365 Teams directly instead of describing what you should do. Microsoft 365 Teams via Graph: list chats, read/send messages, list teams/channels, presence.

What you get

Source-available MCP servers by Mindstone. Works with any MCP host — Claude Desktop, Cursor, Rebel, and others.

Setting it up

Installation goes through your MCP client rather than a global install: point it at @mindstone/mcp-server-zendesk on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

What the assistant can call

Once Microsoft 365 Teams is connected, these are the calls the assistant has available:

  • Release — age cool-down.** The repo-level .npmrc sets min-release-age=7 (days), so CI refuses to install dependency versions published in the last week. This
  • Provenance — attested releases.** Releases are published by CI (.github/workflows/release.yml) under the @mindstone/ npm scope via Trusted Publishing OIDC — no
  • Untrusted — content envelopes.** External content from email, helpdesk, and ticketing systems (email-imap, freshdesk, zendesk) is wrapped in <untrusted-content
  • Secure-by — default writes.** Production-impacting writes (QuickBooks invoices/bills/customers/vendors) require an explicit QB_ALLOW_PROD_WRITES=1 opt-in env
  • Connector — Description

Configuration and credentials

You will need 2 environment variables: MCP_WORKSPACE_PATH, MCP_OAUTH_BIND_HOST. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the microsoft 365 teams mcp server does with a few real requests.

Choosing this one

Among the team communication 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. Microsoft 365 Teams's toolset — Release, Provenance, Untrusted and 2 more — is a fair guide to whether it matches your workflow. It is maintained by mindstone; 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.
