Nothing serious here today

Today is the operative word: we check Microsoft Office every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal

This one needs environment variables set before it will start: MCP_OFFICE_SIDECAR_STATE (Absolute path to sidecar state file (host-managed; sidecar writes port + token here)), MCP_OFFICE_SIDECAR_DISABLE (Kill-switch — set to 1 to refuse to spawn or talk to the sidecar), REBEL_DISABLE_OFFICE_SIDECAR (DEPRECATED legacy alias for MCP_OFFICE_SIDECAR_DISABLE — still honored for backward compatibility with v0.1.1 operator-set kill-switches; will be removed in a future major version. Use MCP_OFFICE_SIDECAR_DISABLE instead.), MCP_OFFICE_SIDECAR_STATE_DIR (Sidecar state directory (certs, per-app manifests). Normally derived from MCP_OFFICE_SIDECAR_STATE; hosts managing the sidecar lifecycle directly can override.), MCP_OFFICE_ADDIN_DIR (Absolute path to the built add-in static files. Defaults to the package's dist/addin/ directory.). The author declared them in the registry entry; get the values from the project itself.

Microsoft Office — questions

Answers built from our own checks of this server.

Why is there no uptime for Microsoft Office?
Microsoft Office runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @mindstone/mcp-server-office was installed 186 times last week.
How do I connect Microsoft Office?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @mindstone/mcp-server-office straight from npm; nothing to host, nothing to sign up for.
How many people use Microsoft Office?
The npm package @mindstone/mcp-server-office was installed 186 times in the last week. Week over week that is +80%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Microsoft Office open source?
We cannot say either way: written in TypeScript, 12 stars on GitHub and 1 open issue, but we could not determine the licence, and without one the code is not open source by default.
