AgentGuard runs on your own machine — the client starts it, so there is no endpoint to ping. 82 installs a week from npm. Last commit 7 Oct 2026.
Local spend caps, kill-switch blocking and Ed25519-signed receipts for AI agent tool calls.
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 7 October 2026. No other catalogue keeps this.

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
