Windsurf Caisy MCP by usefulapi caisy_run_query
How to: Windsurf Caisy MCP by usefulapi caisy_run_query
Add Caisy MCP by usefulapi to Windsurf
-
01
Open ~/.codeium/windsurf/mcp_config.json and merge this in. Keep any servers already there.
{
"mcpServers": {
"caisy": {
"serverUrl": "https://caisy.usefulapi.io/mcp"
}
}
}-
02
Save the file and restart Windsurf.
-
03
Ask for something caisy_run_query does. Windsurf lists the server's tools on connect and calls caisy_run_query itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that Caisy MCP by usefulapi's identifier in your config matches the one above exactly.
Global only — Windsurf has no per-project MCP config. Refresh Cascade after saving. Windsurf docs
Same tool, other clients
This list was read from the server itself, by connecting to it and calling tools/list on 11 November 2026. It is what
the server actually exposes, not what its listing claims.
Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
