Claude Critical Rules MCP server
Gives your AI a built-in safety checklist so it checks, backs up, and asks before touching anything important.
This is a small helper that gives your AI a set of 21 safety rules to follow before it does technical work. It was built from real mistakes people hit in production, like editing the wrong file or deleting something without a backup. It is handy for anyone who lets their AI touch servers, databases, or important documents.
What is an MCP server? The 30-second version
On its own, your AI can only chat with you. An MCP server is a small helper program that gives your AI a new skill or a connection to something outside the chat. This one connects your AI to a rules checklist, so before it starts a risky task it can look up the rules and walk through them. You do not have to remember the rules yourself; the AI reads them from this helper.
What this MCP server does
You ask your AI to do something technical, like deploy a service or edit a config file. The AI calls this helper to pull up a 21-point checklist, grouped into categories like verification, backups, and execution. The helper hands back the rules, a short summary, and version info, and the AI is supposed to confirm each item before it proceeds. It can also check GitHub for newer versions of the rules and install them, keeping a backup of the old ones. You get a more careful, slower, and safer assistant in return.
Click to zoomWhat you can do with it
- Show a 21-point safety checklist before a technical task
- Get a quick summary of all rules grouped by category
- Check the current rules version and compare it to the latest online
- Look for newer rule versions on GitHub
- Download and install updated rules with a backup of the old ones
- Read the full rules document and the changelog as reference
Try asking your AI
- “Before we deploy the new API, run the compliance check and show me the checklist”
- “Give me a summary of all 21 critical rules”
- “Check if there is a newer version of the critical rules”
- “Update the rules to the latest version and tell me what changed”
What it gives back to you
You get text back in the chat: a numbered checklist, a summary of the rules by category, or version details with a note on whether an update is available. If you ask it to update, it reports the result, the verification hash, and where the backup was saved. Nothing is changed on your system except the rules files themselves when you ask for an update.
Before you start
What you need
- The Claude desktop app
- Node.js installed on your computer (the free runtime that runs the helper)
- An internet connection if you want it to check for or install rule updates
Good to know
The update tool downloads files from GitHub and replaces your local rules, so only run it if you trust the source and want the change.
