Install Ground Truth in your MCP client

Ground Truth is a Model Context Protocol server. Add it to your MCP client config once, restart, and the server's tools become available to your AI assistant. The same JSON snippet below works across all four major clients — only the config file path differs.

Locate your client's MCP config file.
- Cursor: ~/.cursor/mcp.json
- Claude Desktop (macOS): ~/Library/Application Support/Claude/claude_desktop_config.json
- Claude Desktop (Windows): %APPDATA%\Claude\claude_desktop_config.json
- VS Code: Settings → Extensions → MCP
- Windsurf: Settings → MCP Servers
Add Ground Truth to the mcpServers map — paste the snippet below into your config file. If you already have other MCP servers, merge the entry into the existing mcpServers object.
Restart your client so it picks up the new server.
Verify — ask the assistant to list available tools; Ground Truth's tools should appear.

  "mcpServers": {
    "ground-truth": {
      "command": "npx",
      "args": [
        "-y",
        "@ground-truth/mcp-server"
      ],
      "note": "Replace with the actual package name from the server's documentation."
    }
  }
}
