Frequently asked questions
Can I send an SMS using the agent?
Yes! Use the send_sms tool with the recipient's phone number and your message content. Your agent will trigger the dispatch through CallFire instantly.
How do I check the status of a specific call?
Simply ask the agent to get_call_details and provide the Call ID. It will retrieve the latest status, such as 'finished' or 'failed', directly from CallFire.
Does the integration allow creating a new voice broadcast?
The current toolset is focused on individual actions and querying (Read-Only/Individual Dispatch) for operational control. Massive broadcasts should be configured via the CallFire web dashboard.
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 CallFire MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
