Frequently asked questions
Can my AI automatically send an email using a SendGrid dynamic template?
Yes! Use the send_email tool. Provide the destination email and the Template ID, and your agent will deliver the message via SendGrid's infrastructure instantly.
How do I check the global email statistics for my account?
Simply ask the agent to run the get_email_stats action. Provide a start date, and it will retrieve aggregate metrics including requests, delivered, opens, and clicks.
How do I find my SendGrid API Key?
Log in to your SendGrid dashboard, navigate to Settings > API Keys, and click 'Create API Key' to generate your unique secret key (SG.xxx).
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 SendGrid MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
