Frequently asked questions
Can I add a new contact to a specific brand using the agent?
Yes! Use the add_contact action with the Brand ID and contact details. Your agent will register or update the subscriber in BigMailer instantly.
How do I list all the email lists for a particular brand?
Simply ask the agent to list_contact_lists and provide the Brand ID. It will retrieve all the mailing lists associated with that brand.
Does the integration allow me to see the statistics of my bulk campaigns?
Yes. Use the get_bulk_campaign tool with the Brand ID and Campaign ID to retrieve performance data and metadata for your marketing efforts.
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 BigMailer MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
