Frequently asked questions
Can I verify if a physical address is valid via AI?
Yes! Use the validate_physical_address tool and provide the address string. Your agent will return the structured, autocompleted data and verification status.
How do I check if an email address is active using the agent?
Use the validate_email tool. Provide the address, and Foxentry will check for syntax, domain validity, and if the specific mailbox actually exists.
Is it possible to retrieve business data using a registration number via AI?
Absolutely. Use the lookup_business_data query and provide the registration number. The agent will retrieve official company names and registered addresses.
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.
