# mega-outlook-mcp [](https://pypi.org/project/mega-outlook-mcp/) [](https://pypi.org/project/mega-outlook-mcp/) [](LICENSE) The most-comprehensive cross-platform MCP server for local Microsoft Outlook automation. **64 tools** across email, threading, calendar, contacts, tasks, notes, inbox rules, automatic replies, free/busy, the Global Address List, and Exchange-specific surface — all behind a single Python package that runs on **both Windows and macOS**. The server is tooling only — scheduling and the agent loop live in your MCP client (LM Studio, Claude Desktop, or any MCP-compatible harness). ## Why mega-outlook-mcp? Two great community MCP servers already exist for Outlook: - [`Aanerud/outlook-desktop-mcp`](https://github.com/Aanerud/outlook-desktop-mcp) — 29 tools, Windows-only, Node.js - [`hasan-imam/mcp-outlook-applescript`](https://github.com/hasan-imam/mcp-outlook-applescript) — 49 tools, macOS-only, Node.js `mega-outlook-mcp` is the union of both, plus more, in one Python package with a unified Backend Protocol. Highlights: - **One install for both OSes.** `pip install mega-outlook-mcp` works the same on Windows and macOS; the right backend is selected at startup. - **Agent-friendly composite tools.** `outlook_summarize_inbox`, `outlook_extract_action_items`, `outlook_find_unanswered`, `outlook_meeting_prep`, `outlook_relationship_graph`, and more — single calls instead of N round trips. - **Exchange-specific surface neither reference repo covers.** Out-of-office, signatures, inbox rules, free/busy lookup, room finder, GAL search, delegated mailboxes, public folders, mailbox quota. - **Built-in compatibility self-test.** `outlook_diagnostics` probes every Outlook field this server depends on and tells you exactly which tools break if Microsoft renames so…
