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.

  const result = spawnSync(javaPath, ["-version"], {

  return path.join(pluginDir, launcherCandidate);

This one needs environment variables set before it will start: MAT_HOME (Path to Eclipse MAT installation directory (e.g., /Applications/MemoryAnalyzer.app/Contents/Eclipse)), JAVA_PATH (Path to Java executable (default: java)), MAT_XMX_MB (Maximum JVM heap size in MB for MAT (default: 4096)). The author declared them in the registry entry; get the values from the project itself.
