Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Dumps the whole environment src/mcpsentinel/discovery.py:366, [пакет] src/mcpsentinel/discovery.py:366

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

MCPSentinel — questions

Answers built from our own checks of this server.

Why is there no uptime for MCPSentinel?

MCPSentinel 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 pypi package mcp-guardian-scan was installed 507 times last week.

How do I connect MCPSentinel?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls mcp-guardian-scan straight from pypi; nothing to host, nothing to sign up for.

How many people use MCPSentinel?

The pypi package mcp-guardian-scan was installed 507 times in the last week. Week over week that is -21%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is MCPSentinel open source?

Yes — it is published under the MIT licence, written in Python and 1 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
