Frequently asked questions
Can I browse inboxes and read emails?
Yes. Browse public and private inboxes, read full email content including HTML, headers, and attachments.
How does Mailinator authentication work?
Mailinator uses a custom Token header for authentication against api.mailinator.com/api/v2.
Can I test SMS messages too?
Yes. Access SMS inboxes and read SMS messages for phone number-based testing.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Mailinator MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
