Control how AI agents use credentials and private data
Delegate scoped API access to AI agents

Keychains.dev provides a credential layer for AI agents calling external APIs. Developers replace credentials in requests with template variables and use its command-line wrapper to send the call. The service injects the appropriate secret on the server, while a user approves the access being requested.
Permissions are scoped to the relevant agent or machine and can be reviewed or revoked from a dashboard. The platform supports OAuth, API keys, and basic authentication, with token refresh and audit records for tracking access. Delegation tools let a parent agent pass limited permissions to another agent. Keychains.dev is intended for applications that need controlled access to users' connected services.
