Your AI acts. You should see what it does.

MCP gave every AI client a universal way to connect to tools. One protocol. Any server. The ecosystem exploded overnight. But it left something out. Nobody built trust into the foundation. You connect a server and hope for the best. You find out what your AI did after it's done.

MCP Firewall exists because trust shouldn't be an afterthought. It sits between your AI and the tools it uses. Every tool call passes through it. You see what's happening, set the boundaries once, and then get out of the way. Enabled tools just work. Risky tools ask first. Blocked tools disappear. Your secrets stay encrypted on your machine. Nothing phones home.

Every tool call passes through the same foundation: the governance model, the approval flow, the audit trail, the encrypted vault. They weren't added over time. They were built together, from the start.

An independent project, built because it should exist. Free for everyone.
