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 pypi package seal-kernel was installed 762 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 seal-kernel straight from pypi; nothing to host, nothing to sign up for.

How many people use Seal?

The pypi package seal-kernel was installed 762 times in the last week. Week over week that is +1149%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Seal open source?

Yes — it is published under the NOASSERTION licence, written in Python and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
