Frequently asked questions
How do I get a Courier Auth Token?
Log in to your Courier dashboard, navigate to Settings > API Keys, and you will find your Auth Token there. Use the 'Published' key for production environments.
What channels are supported?
Courier supports dozens of providers for Email (SendGrid, Mailgun), SMS (Twilio, MessageBird), Push (Firebase, OneSignal), and Chat (Slack, Discord).
Can I track if a message was opened?
Yes, the agent can use the get_message_details tool to check the status of a specific message, which includes tracking events like 'OPENED' or 'CLICKED' if supported by the provider.
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 Courier MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
