      "command": "uvx",
      "args": ["justbuildapps-mcp"]
    }
  }
}

Where the config lives

  • Claude Desktop — claude_desktop_config.json (~/Library/Application Support/Claude/ on macOS)
  • Cursor — .muse/mcp.json (project) or ~/.muse/mcp.json (global)
  • VS Code — .vscode/mcp.json
  • Windsurf — ~/.codeium/windsurf/mcp_config.json

Option B — Hosted remote (zero install)

Point any Streamable HTTP-capable client at our hosted endpoint:

  "mcpServers": {
    "justbuildapps": {
      "type": "streamable-http",
      "url": "https://api.justbuildapps.com/mcp"
    }
  }
}

Same 16 tools, same data — we host it, you just connect. Prefer local (Option A) if you want to pin a version or work offline from our infra.
