Agent Guardrails — questions

Answers built from our own checks of this server.

Why is there no uptime for Agent Guardrails?
Agent Guardrails 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 agent-guardrails was installed 95 times last week.
How do I connect Agent Guardrails?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls agent-guardrails straight from npm; nothing to host, nothing to sign up for.
How many people use Agent Guardrails?
The npm package agent-guardrails was installed 95 times in the last week. Week over week that is -23%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
