Frequently asked questions
How do I find my ChurchStamp Access Token?
Log in to your account, navigate to Settings > Security, and copy your unique Access Token from the API section.
Can I send personalized postcards via AI?
Yes! The send_churchstamp_mail tool allows your agent to trigger physical mailings by providing recipient metadata and design IDs.
How do I list my mail designs?
Use the list_designs tool to retrieve your complete directory along with the unique identifiers for all managed templates.
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 ChurchStamp MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
