Find potential emails quickly

The `email_finder` tool helps your agent extract emails from any known domain. It's a crucial step when you only have the company name and need to build a contact list. Since Pydantic AI enforces strict data types, you can trust that the output structure of this MCP Server call is exactly what you expect.

Automate lead capture via MCP Server

When your agent finds a new contact, use `add_prospect` to log them immediately. This tool takes disparate data points and formalizes them into a single prospect record in Snov.io. The process is type-safe: the resulting data structure is validated against Pydantic models before your code even sees it.

Get detailed contact records

The `get_prospect_by_email` tool lets you retrieve full prospect details using just an email. This gives context that simple search queries miss, allowing for better targeting. Because of Pydantic AI's validation layer, the data returned is guaranteed to match the required schema, eliminating runtime surprises.
