Frequently asked questions
Can my AI automatically find if a specific email exists in a Robly subscriber list?
Yes! Use the exists_in_sub_list tool. Provide the email and the sub_list_id, and your agent will return the membership status and subscription details instantly.
How do I find my Robly API ID and API Key?
Log in to your Robly account, go to My Account (top right), and you will find your unique API ID and API Key listed in the account overview.
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 Robly MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
