FAQ
How many MCP servers are there for SQL querying?
Electra Index lists 790 active MCP servers for SQL querying from the Official MCP Registry. 280 offer a hosted endpoint and 639 publish their source code.
Is there a ready-made AI agent for SQL querying instead?
Yes. If you prefer a finished product to plugging tools into your own assistant, Apollo.io, ThoughtSpot Spotter and Wren AI 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 SQL Querying 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.
