Frequently asked questions
Where do I find my Phone Number ID and Access Token?
Log in to the Meta Developer Portal, select your App, and navigate to the WhatsApp > Getting Started section for the ID, and the App Settings for the System User Access Token.
What is the 24-hour window policy?
WhatsApp restricts business-initiated free-text messages. You can only send free-form text if the user has messaged you in the last 24 hours. Outside this window, you must use a pre-approved Template.
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 WSLA (WhatsApp) MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
