About
AgentKeys is a credential proxy service that prevents AI agents from ever handling real API keys or OAuth tokens. Instead of embedding live credentials into agent configs, you store secrets in AgentKeys and give agents a proxy token (prefixed pxr_). When an agent makes a request, AgentKeys decrypts the real credential server-side, forwards the call, and returns the response — your actual keys never leave the platform. It supports API keys, OAuth with auto-refresh, Basic Auth, custom headers, and cookies, and works with OpenClaw, LangChain, CrewAI, AutoGPT, and MCP servers.
Development teams and solo builders who run AI agents that need access to third-party APIs and want to avoid the security risk of pasting real credentials into agent configuration files or prompts. Particularly useful in multi-tenant scenarios where different agents need scoped access to separate credential sets. <!-- Screenshot pending -->
Pros & Cons
Pros
- check Eliminates credential exposure in agent configs, logs, and memory — a meaningful security improvement over the common pattern of hardcoding keys
- check AES-256-GCM encryption with per-workspace master keys and zero plaintext storage gives a credible security baseline
- check Full audit log captures agent identity, target URL, status code, and latency for every request — useful for both debugging and compliance
- check Automatic OAuth token refresh handles expiry for Google, GitHub, Slack, Notion, HubSpot, and others without manual intervention
- check Open-source core for the encryption and proxy logic allows independent audit
Cons
- close Free tier is very limited: 3 credentials, 1 agent, and 100 requests per month, which is only useful for testing
- close Adds a network hop to every agent API call — latency impact is small but nonzero, and the proxy becomes a dependency for agent uptime
- close Self-hosting is not mentioned as an option, so teams with strict data residency requirements may be blocked
- close Vendor lock-in risk: if AgentKeys goes offline or changes pricing, every agent that depends on proxy tokens stops working
