What the code does

We read the source, 5 d ago · rules 995398eba69f

In the project's build, not in the package

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

Dumps the whole environment src/services/LoginShellEnvironment.swift:133

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

Nothing serious here today

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

Blitz — questions

Answers built from our own checks of this server.

Why is there no uptime for Blitz?
Blitz 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 @blitzdev/blitz-mcp was installed 52 times last week.
How do I connect Blitz?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls @blitzdev/blitz-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Blitz?
The npm package @blitzdev/blitz-mcp was installed 52 times in the last week. Week over week that is +271%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Blitz open source?
Yes — it is published under the Apache-2.0 licence, written in Swift, 1 765 stars on GitHub and 6 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
