Cursor

Create .cursor/mcp.json in your project (or ~/.cursor/mcp.json for all projects):

{
  "mcpServers": {
    "protobox": {
      "type": "streamablehttp",
      "url": "https://your-workspace.protobox.app/mcp",
      "headers": { "X-API-Key": "YOUR_API_KEY" }
    }
  }
}

Open Cursor's MCP settings — protobox should show as connected with your tools listed. If not: protobox mcp test, then check the JSON.
