keychains.dev

Keychains.dev is a secure credential proxy for AI agents. Use "keychains curl" as a drop-in for curl — just replace hard-coded credentials with template variables like {{GITHUB_TOKEN}}. Keychains injects real credentials server-side. Your agent never sees raw secrets — immune to prompt injection by design. Users approve each permission with one click and can revoke access anytime. Full audit trail. Works with 11,000+ API providers (OAuth, API keys, basic auth).
