Frequently asked questions
How can I see all cards belonging to a specific person?
Use the list_cards_by_user tool by providing the user's unique token. The agent will return a list of all physical and virtual cards associated with that account holder.
How do I add money to a user's card account?
You can use the create_gpa_order tool. You'll need the user token, the amount, currency code, and a funding source token to move funds into their General Purpose Account.
Is it possible to register a legal entity instead of an individual?
Yes, use the create_business tool to create a business entity. You can then retrieve its details using the get_business tool with the business token.
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.
