Frequently asked questions
Where do I find my ZeptoMail Send Mail Token?
Log in to Zoho ZeptoMail, go to your Mail Agent, and navigate to the 'API' section to generate a token.
Which Zoho regions are supported for ZeptoMail?
We support US, EU, IN, AU, and CN data centers. Make sure to select the region where your ZeptoMail account is hosted.
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 Zoho ZeptoMail MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
