What the code does

We read the source, 3 d ago · rules 995398eba69f

Evidence

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

Capabilities

Agent Security Scanner MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Agent Security Scanner MCP?

Agent Security Scanner MCP runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package agent-security-scanner-mcp was installed 459 times last week.

How do I connect Agent Security Scanner MCP?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls agent-security-scanner-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Agent Security Scanner MCP?

The npm package agent-security-scanner-mcp was installed 459 times in the last week. Week over week that is -24%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Agent Security Scanner MCP open source?

Yes — it is published under the MIT licence, written in JavaScript, 123 stars on GitHub and 2 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
