Windsurf Filesystem directory_tree

Add Filesystem to Windsurf

1. 01

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

{
  "mcpServers": {
    "server-filesystem": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-filesystem"
      ]
    }
  }
}

2. 02

   Save the file and restart Windsurf.

3. 03

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

4. 04

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