Frequently asked questions
How do I find my Flodesk API Key?
Log in to your Flodesk account, navigate to Settings > Integrations > API keys, and click Generate new key.
Can I search for a subscriber by email?
Yes! Use the get_subscriber tool and provide the email address to retrieve their profile, segments, and status.
How do I trigger an automation for a subscriber?
Use the add_subscriber_to_workflow tool by providing the unique workflow_id and the subscriber's ID or email address.
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 Flodesk MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
