Windsurf ipvolt Proxy Toolkit diagnose_proxy_error

How to: Windsurf ipvolt Proxy Toolkit diagnose_proxy_error

client:Windsurf transport:streamable-http tool:diagnose_proxy_error

Add ipvolt Proxy Toolkit to Windsurf

01
Open ~/.codeium/windsurf/mcp_config.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "proxy-toolkit": {
      "serverUrl": "https://mcp.ipvolt.com/mcp"
    }
  }
}

02
Save the file and restart Windsurf.
03
Ask for something diagnose_proxy_error does. Windsurf lists the server's tools on connect and calls diagnose_proxy_error itself — you do not invoke it by name.
04
If nothing happens, check the server is running and that ipvolt Proxy Toolkit'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

Set these first

ipvolt Proxy Toolkit will not start until these are set, so diagnose_proxy_error never becomes available.

IPVOLT_ENABLE_ROUTE_CHECK
IPVOLT_PROXY_URL

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 24 September 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.
