Frequently asked questions
Can I use this server to actually send operational emails from my account?
Yes! The send_email and send_email_with_template tools will dispatch active live emails using your Postmark server configuration.
How can I debug a specific user reporting that they didn't receive an email?
You can ask the agent to execute search_outbound_messages or search_bounces using their exact email address. The agent will fetch the delivery log and status codes.
Do I need the Account Token or the Server Token to use this?
You only need the Server Token. Postmark divides workflows by servers (environments). Supplying the server token isolates this specific operational environment perfectly.
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.
