Frequently asked questions
How do I find my Mailshake API Key?
Log in to Mailshake, navigate to 'Extensions' in the main menu, and select 'API' to generate or copy your personal API key.
What is the difference between a Lead and a Recipient?
A Recipient is anyone added to a campaign. A Lead is a recipient who has met specific engagement criteria (like replying) and is tracked in the 'Lead Catcher'.
Can I add multiple prospects at once?
Yes, the add_prospects_to_campaign tool accepts a JSON body where you can provide a list of multiple recipients to be added in a single request.
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 Mailshake MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
