If you need the other direction, ask: your agent reads Harvestr's API documentation and adds it. ### ### Do I have to build a connector for MailCheck.ai or Harvestr? No. Both are in the catalog with their triggers and actions.

It plans the failure paths along with the happy path, then tests every scenario before it ships. ### ### Is there a free plan? Yes.
