Frequently asked questions
Can I capture only a specific part of a webpage?
Yes! Use the render_selector tool. Provide the URL and the CSS selector (e.g., #my-chart) to capture only that specific element instead of the whole page.
How do I see how many credits I have left?
Run the get_credit_usage query. Your agent will retrieve your current credit balance and monthly rendering metrics directly from Urlbox.
Can this tool convert a URL directly to PDF?
Absolutely. Use the capture_pdf tool by providing the URL. You can also specify an optional page size like 'A4' or 'Letter'.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
