Frequently asked questions
How do I get my Cometly API key?
Log in to Cometly, go to Account Settings > API Keys, copy your key, and paste it below.
Is this the same as Meta Conversions API (CAPI)?
No. Cometly acts as a bridge: it receives events, attributes them, and syncs data back to Meta, Google, TikTok, etc.
What event types are supported?
Standard events: Purchase, Lead, Add To Cart, Initiate Checkout. You can also use custom event names.
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 Cometly MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
