Argus MCP Server

One line in your MCP config gives Claude (or any MCP agent) a real Chrome audit engine - 67 audit categories · 149 finding types · zero test files to write or maintain. And with Aegis, what it finds never leaks your secrets to the LLM. It runs locally over stdio via the published package.

People who work with automation, chrome devtools and npm package and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.
