Frequently asked questions
Can I see all the subscribers in a specific list via AI?
Yes! Use the list_acelle_subscribers tool and provide the List UID. Your agent will retrieve the directory of members associated with that mailing list.
How do I add a new subscriber to a list using the agent?
Use the add_acelle_subscriber action. Provide a JSON object with the subscriber's details, including 'EMAIL' and the target 'list_uid'. The agent will instantly register the new member.
Is it possible to check the status of my email campaigns via AI?
Absolutely. Use the list_acelle_campaigns query. The agent will retrieve all your active and past campaigns, allowing you to monitor their delivery status and performance metrics.
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 Acelle Mail MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
