Windsurf ensembl mcp server ensembl_predict_variant

How to: Windsurf ensembl mcp server ensembl_predict_variant

client:Windsurf transport:streamable-http tool:ensembl_predict_variant

Add ensembl mcp server to Windsurf

  1. 01

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

{
  "mcpServers": {
    "ensembl-mcp-server": {
      "serverUrl": "https://ensembl.caseyjhand.com/mcp"
    }
  }
}
  1. 02

    Save the file and restart Windsurf.

  2. 03

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

  3. 04

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

ensembl mcp server will not start until these are set, so ensembl_predict_variant never becomes available.

  • ENSEMBL_BASE_URL
  • MCP_LOG_LEVEL

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.
