AegisMCP

Security between AI and action

What it does

AegisMCP is an open-source AI Agent Firewall for the Model Context Protocol (MCP). It protects sensitive resources by isolating credentials, enforcing policy-based access control, and inspecting every tool request before execution. With threat scoring, real-time monitoring, and tamper-evident audit logs, AegisMCP gives developers a secure, transparent way to deploy AI agents without exposing secrets or critical systems.

    Background: I've been working on agentic guardrails because agents act in expensive/terrible ways and something needs to be able to say "Maybe don't do that" to the agents, but guardrails are almost impossible to enforce with the current way things are built. Context: We keep running into so many problems/limitations today with MCP. It was created so that agents have context on how to act in the world, it wasn't designed to become THE standard rails for agentic behavior. We keep tacking things on to it trying to improve it, but it needs to die a SOAP death so REST can rise in it's…

    Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
