Keychains.dev

Keychains.dev is a secure credential orchestration layer designed for AI agents that need to call external APIs without exposing secrets. It enables developers and organizations to let LLMs and autonomous agents interact with third-party services while keeping API keys, tokens, and other sensitive credentials fully protected and under user control. The platform focuses on secure, auditable access rather than embedding secrets directly into prompts, code, or agent runtimes.

At its core, Keychains.dev uses SSH-secured tunnels and a permissioned keychain model to broker access to APIs. Developers can define fine-grained, revocable permissions that specify which services an agent can call and under what conditions, without ever revealing the underlying credentials. The system supports per-user and per-agent key segregation, making it easier to enforce least-privilege access and rotate or revoke keys without code changes. Detailed logging and access controls provide transparency into which agents accessed which APIs and when.
