Frequently asked questions
Can I create and track email campaigns?
Yes. Create campaigns, send to subscriber segments, and track open rates, click rates, bounces, and unsubscribes in real time.
How does Maildroppa authentication work?
Maildroppa uses a custom X-API-Key header (not Bearer) against api.maildroppa.com.
Can I manage subscriber lists and segments?
Yes. Create and manage subscriber lists, add/remove subscribers, and build segments with custom conditions.
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 Maildroppa MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
