About
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).
Use Cases
- Replace hard-coded API credentials with {{TEMPLATE_VARIABLES}} for server-side secret injection, eliminating credential exposure in logs
- Connect agents to 11,000+ APIs (GitHub, Stripe, Salesforce, etc.) with one-time authentication and granular revocable per-permission access
- Use 'keychains curl' as drop-in curl replacement in agent workflows with full audit trails of credential access
- Implement OAuth, API key, and basic auth flows transparently without storing secrets in environment variables or databases
- Let end-users approve individual API permissions via one-click consent and monitor access history through audit trails
