Frequently asked questions
Can I see the most common reason users are trying to cancel?
Yes! Use the get_session_aggregates tool. The agent will return grouped data showing which reasons are being selected most frequently in your cancellation flows.
How do I update the billing contact for a customer whose payment failed?
Use the update_billing_contacts tool. Provide the customer ID and the new contact details. This ensures Churnkey sends dunning and recovery emails to the right person.
Where do I find my Churnkey Data API Key and App ID?
Log in to your Churnkey dashboard and navigate to Settings > Account. You can find your App ID and generate a Data API Key in the API section.
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 Churnkey MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
