agent-secrets
Encrypted secrets management MCP server for AI agents, enabling secure storage, retrieval, rotation, and auditing of API keys and credentials with AES-128 encryption.
README
agent-secrets
Encrypted secrets management MCP server for AI agents. Store, retrieve, rotate, and audit API keys, tokens, and credentials — all encrypted at rest.
Why
AI agents need access to API keys, tokens, and credentials. Hardcoding them or passing via env vars is insecure and unmanageable at scale. agent-secrets provides a single encrypted vault with audit trails, access policies, and rotation — exposed as MCP tools any agent can call.
Features
- AES-128 encryption at rest (Fernet: AES-128-CBC + HMAC-SHA256)
- 14 MCP tools: store, get, list, update, rotate, revoke, delete, search, audit, policies, batch, stats
- Access policies: allow/deny patterns, type restrictions
- Full audit log: every access tracked
- Secret rotation: rotate with history
- CLI + MCP server: use from terminal or any MCP-compatible agent
