MCP Slim Guard — questions

Answers built from our own checks of this server.

Why is there no uptime for MCP Slim Guard?
MCP Slim Guard 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 mcp-slim-guard was installed 153 times last week.
How do I connect MCP Slim Guard?
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-slim-guard straight from npm; nothing to host, nothing to sign up for.
How many people use MCP Slim Guard?
The npm package mcp-slim-guard was installed 153 times in the last week. Week over week that is +20%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is MCP Slim Guard open source?
Yes — it is published under the MIT licence, written in TypeScript and 12 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.
