Type-safe subscriber creation with Pydantic AI

Stop worrying about silent API failures or corrupted contact records when your agent runs `create_pabbly_subscriber` with Pydantic AI validation. The framework validates the email format and custom fields against strict schemas before execution. If the Pabbly API returns an unexpected payload, our MCP integration raises a validation error immediately. This keeps your subscriber database clean and prevents malformed data from breaking downstream processes.

Validated campaign tracking via Pydantic AI

Fetch your marketing metrics with absolute structural certainty by letting your agent use `list_pabbly_campaigns` and `get_pabbly_campaign` to inspect delivery rates and open statistics. The framework parses these metrics into typed Python models at runtime. You can build automated reports knowing that every campaign ID and subscriber count matches your expected data types.

Schema-guaranteed list management

Manage your audience segments safely by calling `create_pabbly_list` and `list_pabbly_lists`. Pydantic AI ensures that list metadata conforms exactly to your application's internal types. When verifying active web forms, the agent runs `list_pabbly_forms` to match form fields with your CRM. Any structural mismatch triggers an immediate alert, stopping bad integrations in their tracks.
