Aegis

Aegis is an open-source MCP (Model Context Protocol) server that provides credential isolation and security for AI agents. It acts as a local, transparent proxy between AI assistants (like Claude, Cursor, and Windsurf) and the APIs they access, injecting secrets only at the network boundary. Aegis enforces access controls, domain restrictions, audit logging, and robust security features without ever exposing raw credentials to the agent. It integrates with systems such as Slack, GitHub, Stripe, and any HTTP API, and is intended for teams and developers using AI agents that require secure, controlled API access in development or production environments.
