About the PostHog MCP server

Connect PostHog once in Activepieces and every action it ships becomes a tool your assistant can call, behind the same server URL as the rest of your apps. Your agent reaches PostHog and 760+ other apps over a single connection, on our cloud or a self-hosted install.

PostHog MCP, answered.

No. That is the point of it. One Activepieces server exposes PostHog 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 PostHog 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 5 tools, including Capture Event, Create Project, Get Feature Flags, 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.
