01 · Install Ctxfile

Claude Code

claude mcp add ctxfile-ctxfile -- npx -y ctxfile

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "ctxfile-ctxfile": {
      "command": "npx",
      "args": [
        "-y",
        "ctxfile"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
