Windsurf QuickBuild agent tools (x402) free_site_check
How to: Windsurf QuickBuild agent tools (x402) free_site_check
Add QuickBuild agent tools (x402) to Windsurf
-
01
Open ~/.codeium/windsurf/mcp_config.json and merge this in. Keep any servers already there.
{
"mcpServers": {
"agent-tools": {
"serverUrl": "https://quickbuild.quynguyenbac.workers.dev/mcp"
}
}
}-
02
Save the file and restart Windsurf.
-
03
Ask for something free_site_check does. Windsurf lists the server's tools on connect and calls free_site_check itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that QuickBuild agent tools (x402)'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 20 October 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.
