Frequently asked questions
How do I find my Apptoto API Key and Secret?
Log in to your account, navigate to Settings > Advanced > API, and generate or copy your unique credentials.
Can I list my connected address books via AI?
Yes! The list_address_books tool allows your agent to retrieve all contact directories currently synced with your Apptoto account.
How do I check sent reminder messages?
Use the list_messages tool to retrieve high-fidelity historical records of all SMS and email communications dispatched programmatically.
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 Apptoto MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
