Cosync Local

Handles local encryption and project initialization for CoSync without sending your keys over the network. This is the client-side companion that keeps sensitive cryptographic material on your machine while you set up CoSync projects. Reach for this when you need to configure CoSync locally and want to avoid transmitting private keys to any external service. The stdio transport means it runs as a local process that Claude can invoke directly. Without more implementation details in the source, the core value proposition is straightforward: local-first security for CoSync project setup where your encryption keys stay put.
