Nothing serious here today

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

This one needs environment variables set before it will start: AGENT_WALLET_PRIVATE_KEY (Private key of a Base wallet holding USDC, used to pay SENTINEL autonomously via x402). The author declared them in the registry entry; get the values from the project itself.

SENTINEL — questions

Answers built from our own checks of this server.

Why is there no uptime for SENTINEL?

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 pypi package sentinel-mcp was installed 51 times last week.

How do I connect 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 sentinel-mcp straight from pypi; nothing to host, nothing to sign up for.

How many people use SENTINEL?

The pypi package sentinel-mcp was installed 51 times in the last week. Week over week that is -43%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
