A Microsoft Teams MCP server lets AI agents read and write Microsoft Teams data through the Model Context Protocol — Anthropic's open standard for connecting LLMs to external tools. StackOne's Microsoft Teams MCP server ships with 75 pre-built actions, fully extensible via the Connector Builder — plus managed authentication, prompt injection defense, observability, and agent execution runtime. Connect it from MCP clients like Claude Desktop, Claude Code, Cursor, Goose, and VS Code, or from agent frameworks like OpenAI Agents SDK, LangChain, and Vercel AI SDK.
All Microsoft Teams MCP Tools
Every action from Microsoft Teams's API, ready for your agent. Create, read, update, and delete — scoped to exactly what you need.
