Nothing serious here today

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

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add GuardianShield -- uvx guardianshield
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "GuardianShield": {
      "args": [

This one needs environment variables set before it will start: GUARDIANSHIELD_PROFILE (Default safety profile (general, education, healthcare, finance, children)), GUARDIANSHIELD_AUDIT_PATH (Path to the SQLite audit database), GUARDIANSHIELD_DEBUG (Set to 1 for debug logging). The author declared them in the registry entry; get the values from the project itself.

GuardianShield — questions

Answers built from our own checks of this server.

Why is there no uptime for GuardianShield?
GuardianShield 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 guardianshield was installed 82 times last week.
How do I connect GuardianShield?
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 guardianshield straight from pypi; nothing to host, nothing to sign up for.
How many people use GuardianShield?
The pypi package guardianshield was installed 82 times in the last week. Week over week that is -33%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is GuardianShield open source?
Yes — it is published under the Apache-2.0 licence, written in Python, 3 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.
