MCP Server · GenMB feature

Turn your app into an MCP server

The Model Context Protocol is how AI clients call tools. GenMB lets you expose your app as an MCP server - so Claude and other MCP-aware clients can drive it directly - and ships OAuth connectors so your generated apps can reach Gmail, Slack, Notion, HubSpot, Calendar, and Outlook.

Frequently asked

What does exposing my app as an MCP server do?

It lets MCP-aware AI clients like Claude call your app as a tool - looking up data, triggering actions, and reading results through a standard protocol instead of a bespoke integration.

Does MCP cost extra?

Connecting over MCP is free - the connecting client pays for its own inference. Exposing a backend function as a tool is free on every plan; listing the app in the public MCP registry, issuing API keys, and client mode are paid capabilities.

How do I make my own app callable by an agent?

Write a backend function, add an @description and an @param line per input, then turn on "Expose as MCP tool" in the Functions panel. See the full walkthrough at /agent-ready.
