Frequently asked questions
Can I view balances and recent transactions?
Yes. You can query balances for all accounts and list recent incoming/outgoing transactions.
How does Mercury authentication work?
Mercury uses a Bearer token (API Token) against api.mercury.com/api/v1. Tokens must be generated with read-only scopes.
Can I initiate money transfers via the API?
The standard API token allows read-only access to balances and transactions for security reasons.
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.
