Perplexity

Type-safe email tools for Pydantic AI

Every response from `get_contacts` is validated against strict Pydantic models. Your agent crashes safely if the API returns malformed data. Use `create_contact` to add records while ensuring all fields meet your schema requirements. It prevents bad data from entering your marketing pipeline.

MCP server reliability for Pydantic AI

The toolset works with your agent to ensure every call to `update_list` matches expected structures. You get clear errors if inputs are wrong. Monitor campaign status with `get_activity_status`. Your agent checks the result type before proceeding to the next step.

Precise marketing automation

Manage tags with `create_tag` and verify success with `get_tags`. Your agent keeps your contact database clean and well-structured. Use `export_contacts` to extract data for local analysis. Pydantic AI ensures the output format remains consistent every time.
