VS Code Highwire build_trade

How to: VS Code Highwire build_trade

client:VS Code transport:streamable-http tool:build_trade

Add Highwire to VS Code

01
Open .vscode/mcp.json and merge this in. Keep any servers already there.

{
  "servers": {
    "highwire": {
      "type": "http",
      "url": "https://highwire.fun/mcp"
    }
  }
}

02
Save the file and restart VS Code.
03
Ask for something build_trade does. VS Code lists the server's tools on connect and calls build_trade itself — you do not invoke it by name.
04
If nothing happens, check the server is running and that Highwire's identifier in your config matches the one above exactly.

Requires agent mode. MCP: Open User Configuration puts the same block in every workspace. VS Code docs

Set these first

Highwire will not start until these are set, so build_trade 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.
