Windsurf Epsilon get_orderbook

How to: Windsurf Epsilon get_orderbook

client:Windsurf transport:streamable-http tool:get_orderbook

Add Epsilon to Windsurf

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

{
  "mcpServers": {
    "epsilon": {
      "serverUrl": "https://api.epsilon.exchange/mcp"
    }
  }
}

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

Epsilon will not start until these are set, so get_orderbook never becomes available.

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.
