Frequently asked questions
Can I search for a contact by phone number?
Yes! Use search_contacts with the phone number to find matching contacts in your Chiirp database.
How do I add a tag to trigger an automation?
Use apply_tag with the contact's phone number and the tag ID. If the tag is linked to an automation sequence in Chiirp, it will trigger automatically.
Can I view my active campaigns?
Yes! Use list_campaigns to see all SMS and drip campaigns, or list_sequences to view automation workflows with their statuses.
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 Chiirp MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
