Infisical

Infisical is an open-source identity security platform for managing application secrets, certificates, and privileged access across cloud, on-premises, and AI infrastructure. It provides centralized storage, rotation, scoped access controls, approval workflows, and auditing for credentials.

Its Agent Proxy lets AI agents access approved tools and APIs without exposing real credentials in the agent environment. Agents receive placeholders, while the proxy attaches the underlying secrets, restricts which services they can reach, routes requests through an auditable layer, and records each request. The platform's site says the proxy supports more than 30 services.
