Frequently asked questions
How do I find my DoubleTick API Key?
Log in to your DoubleTick account, navigate to Settings > Developer API, and generate or copy your unique access token.
Do I need approved templates to send messages?
Yes, for business-initiated conversations, the WhatsApp Business API requires using templates that have been approved by Meta.
How do I handle template placeholders?
The send_template_message tool accepts a placeholders_json string. Provide a JSON array containing the values for your template variables in order.
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 DoubleTick MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
