Environment variables
  • MCP_LOG_LEVELSets the minimum log level for output (e.g., 'debug', 'info', 'warn').
  • CLIPBOARD_READ_ONLYServe the clipboard read-only. When true, clipboard_write is not registered: it is absent from tools/list and uncallable, absent from the manifest but shown as disabled on the landing page and startup log. Accepts true/false/1/0/yes/no/on/off.

A starting point — check the repository for exact arguments and setup. Restart your client after editing the config.
