Localfig MCP Server

What the code does

We read the source, 18 h ago · rules 3dff92dd89df

A value the model can set ends up inside a file or shell call. That is not a flaw by itself — for a terminal server it is the job — but it is where things go wrong when it is not.

      const bytes = fs.readFileSync(args.filePath);

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.

    return spawnSync(process.env.ComSpec || 'cmd.exe', ['/d', '/s', '/c', '"' + [file].concat(args).map(q).join(' ') + '"'], { encoding: 'utf8', windowsVerbatimArguments: true });

    const dst = path.join(PLUGIN_DIR, file);
