Evidence

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

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.

Checks whether it runs in a sandbox apps/cli/src/isolation.ts:58
      existsSync("/.dockerenv") || existsSync("/run/.containerenv"),
    const child = spawn(claude, claudeLaunchArgv(file, passed), { cwd: env.workspaceRoot, stdio: "inherit" });
Touches key and credential files Dockerfile:10

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

We found things in this code

Code changes quietly between releases, and nobody reads the diff of a dependency. We do, on every release — watch MELRA and you get told the day something new turns up.

MELRA — questions

Answers built from our own checks of this server.

Why is there no uptime for MELRA?
MELRA 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 @melra/cli was installed 722 times last week.
How do I connect MELRA?
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 @melra/cli straight from npm; nothing to host, nothing to sign up for.
How many people use MELRA?
The npm package @melra/cli was installed 722 times in the last week. Week over week that is +14340%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is MELRA open source?
Yes — it is published under the Apache-2.0 licence, written in TypeScript, 12 stars on GitHub and 18 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
