Koma Gate MCP Server

local only

Koma Gate MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 15 installs a week from npm. Last commit 13 Oct 2026.

Classifies prompt injection, jailbreaks, and out-of-scope user input before agents act on it.

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.

    const result = spawnSync(process.execPath, [live], { stdio: 'inherit' });
Builds a file path from a variable packages/koma-miko/src/init.ts:289
  const settingsPath = path.join(projectRoot, details.settingsRelativePath);

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 Koma Gate MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Koma Gate MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Koma Gate MCP?
Koma Gate 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 koma-gate-mcp was installed 15 times last week.
How do I connect Koma Gate MCP?
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 koma-gate-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Koma Gate MCP?
The npm package koma-gate-mcp was installed 15 times in the last week. Week over week that is -15%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Koma Gate MCP open source?
Yes — it is published under the MIT licence, written in TypeScript, 13 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.
