This one needs environment variables set before it will start: SERIAL_MCP_MAX_CONNECTIONS (Maximum simultaneous open serial connections (default 10)), SERIAL_MCP_PLUGINS (Plugin policy: 'all' or comma-separated plugin names. Unset = disabled.), SERIAL_MCP_MIRROR (PTY mirror mode: 'off' (default), 'ro' (read-only), or 'rw' (read-write). macOS/Linux only.), SERIAL_MCP_MIRROR_LINK (Base path for PTY symlinks (default /tmp/serial-mcp when mirror is enabled). Connections get numbered: /tmp/serial-mcp0, /tmp/serial-mcp1, etc.), SERIAL_MCP_TOOL_SEPARATOR (Tool name separator character (default '.'). Set to '_' for clients that reject dots (e.g. Cursor).). The author declared them in the registry entry; get the values from the project itself.
