FAQ
How many MCP servers are there for API integration?
Electra Index lists 386 active MCP servers for API integration from the Official MCP Registry. 191 offer a hosted endpoint and 313 publish their source code.
Is there a hosted MCP server for API integration, with nothing to install?
Yes. Openhook, HotAPI Docs and Ssemble AI Clipping declare a remote endpoint you add to your assistant's MCP settings.
Is there a ready-made AI agent for API integration instead?
Yes. If you prefer a finished product to plugging tools into your own assistant, Jamie, MeetGeek and Ramp (AI agents) do this out of the box.
How this list is ordered: a tool comes first when the use case appears in its name rather than only in its description, then when it offers a hosted endpoint, then when its source code is public, then by how recently our robot saw it in the Official MCP Registry. The match to API Integration comes from the publisher's description (keyword method), not from a test of the tool. Only active tools with a real description are listed. No tool pays to appear here.
