Windsurf Highwire rug_check

How to: Windsurf Highwire rug_check

client:Windsurf transport:streamable-http tool:rug_check

Add Highwire to Windsurf

  1. 01

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

{
  "mcpServers": {
    "highwire": {
      "serverUrl": "https://highwire.fun/mcp"
    }
  }
}
  1. 02

    Save the file and restart Windsurf.

  2. 03

    Ask for something rug_check does. Windsurf lists the server's tools on connect and calls rug_check itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that Highwire'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

Highwire will not start until these are set, so rug_check never becomes available.

  • HIGHWIRE_CLUSTER
  • SOLANA_RPC_URL
  • HIGHWIRE_KEYPAIR_PATH

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 6 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.
