Frequently asked questions
Can I verify if an email address is valid via AI?
Yes! Use the verify_email_address tool and provide the address. Your agent will return its status (Valid, Invalid, etc.) and deliverability score.
How do I find a person's professional email using the agent?
Use the find_prospect_email tool. Provide the person's full name and their company domain (e.g., 'example.com'). Clearout will attempt to locate the verified address.
Is it possible to check my remaining API credits via AI?
Absolutely. Use the check_api_credits query. The agent will retrieve your current account balance, helping you monitor your validation budget.
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.
