What the code does

We read the source, 18 h ago · rules 3dff92dd89df

In the project's build, not in the package

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

Builds a database query by concatenation .github/workflows/publish.yml:41
      - name: Update server.json version
        run: |
          VERSION=${{ steps.version.outputs.VERSION }}

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

Nothing serious here today

Today is the operative word: we check Code Sentinel every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Code Sentinel — questions

Answers built from our own checks of this server.

Why is there no uptime for Code Sentinel?
Code Sentinel 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 code-sentinel-mcp was installed 51 times last week.
How do I connect Code Sentinel?
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 code-sentinel-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Code Sentinel?
The npm package code-sentinel-mcp was installed 51 times in the last week. Week over week that is -14%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Code Sentinel open source?
We cannot say either way: written in TypeScript and 3 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
