Frequently asked questions
How do I find my EmailOctopus API Key?
Log in to your account, navigate to Integrations > API, and click Create Key to generate your unique access token.
Can I update custom fields for a contact?
Yes! The update_contact_profile tool allows you to modify tags and any custom data fields associated with a subscriber.
How do I check the performance of a sent campaign?
Use the get_campaign_summary_report tool with a campaign ID to retrieve real-time metrics including open and click rates.
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 EmailOctopus MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
