This one needs environment variables set before it will start: CLIENT_PRIVATE_KEY (A Base wallet holding USDC on-chain (no gas needed) — pays per call, from $0.002.), SENTINEL_URL (Override the service base URL (default https://402sentinel.com).). The author declared them in the registry entry; get the values from the project itself.

402sentinel MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for 402sentinel MCP?

402sentinel MCP 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 @kaditang/402sentinel-mcp was installed 38 times last week.

How do I connect 402sentinel MCP?

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 @kaditang/402sentinel-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use 402sentinel MCP?

The npm package @kaditang/402sentinel-mcp was installed 38 times in the last week. Week over week that is +21%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is 402sentinel MCP open source?

We cannot say either way: written in TypeScript and 1 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
