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

SEAL — questions

Answers built from our own checks of this server.

Why is there no uptime for SEAL?

SEAL 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 sealnet-mcp was installed 320 times last week.

How do I connect SEAL?

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 sealnet-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use SEAL?

The npm package sealnet-mcp was installed 320 times in the last week. Week over week that is -62%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
