Frequently asked questions
Can my AI automatically add a new subscriber to a specific group by providing their email?
Yes! Use the create_subscriber tool. Provide the email address and an array of Group IDs, and your agent will create the record and assign them instantly.
How do I check the performance statistics for a recently sent campaign?
Simply ask the agent to run the get_campaign_stats action with the Campaign ID. It will retrieve the detailed metadata, including opens, clicks, and bounces.
How do I find my Sender.net API Token?
Log in to your Sender.net dashboard, navigate to Settings > API access tokens, and you will find or generate your unique Bearer token there.
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 Sender.net MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
