FAQ
How many MCP servers are there for knowledge base QA?
Electra Index lists 504 active MCP servers for knowledge base QA from the Official MCP Registry. 239 offer a hosted endpoint and 382 publish their source code.
Is there a ready-made AI agent for knowledge base QA instead?
Yes. If you prefer a finished product to plugging tools into your own assistant, Jamie, Notion Agent and Fathom 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 its description covers more aspects of the use case, 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 knowledge Base QA 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.
