Windsurf EventTrader MCP board_subscribe

How to: Windsurf EventTrader MCP board_subscribe

client:Windsurf transport:streamable-http tool:board_subscribe

Add EventTrader MCP to Windsurf

  1. 01

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

{
  "mcpServers": {
    "event-trader-mcp": {
      "serverUrl": "https://cymetica.com/mcp/v1"
    }
  }
}
  1. 02

    Save the file and restart Windsurf.

  2. 03

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

  3. 04

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

EventTrader MCP will not start until these are set, so board_subscribe never becomes available.

  • EVENT_TRADER_API_KEY
  • EVENT_TRADER_API_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.
