About the Vapi MCP server

Connect Vapi 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 Vapi and 770+ other apps over a single connection, on our cloud or a self-hosted install.

Vapi MCP, answered.

No. That is the point of it. One Activepieces server exposes Vapi 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 Vapi 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 Call, Get Call, Update Assistant, 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.
