Microsoft Outlook Calendar MCP, answered.

No. That is the point of it. One Activepieces server exposes Microsoft Outlook Calendar alongside every other piece you connect, so your client keeps a single connection.

Yes. Activepieces is open source and free to start, and the MCP server is included on every plan, from the free cloud tier to any self-hosted deployment.

Connect Microsoft Outlook Calendar in Activepieces, enable the server under Settings → MCP Server, then paste your server URL into your client config. It authenticates over OAuth on first use.

It can call 4 tools, including Create a new event in a calendar, Delete an event in a calendar, List events in a calendar, and chain them with steps in other apps inside the same run.

Connections use OAuth2 with limited scopes and are stored under 256-bit encryption, with no API to read them back, so an agent gets scoped access rather than your keys.
