Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Runs an external command lib/launcher-common.js:100, [пакет] lib/launcher-common.js:100

  const child = spawn(file, args, { stdio: "inherit", env });

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

Blowhorn — questions

Answers built from our own checks of this server.

Why is there no uptime for Blowhorn?

Blowhorn 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 blowhorn-mcp.

How do I connect Blowhorn?

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

Is Blowhorn open source?

Yes — it is published under the AGPL-3.0 licence, written in JavaScript, 0 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
