What it needs

  • OMA_DBOptional. Path to the SQLite store. Defaults to a fixed per-user data directory; set this to isolate a store.
  • OMA_VIEWEROptional. Browser viewer on loopback. On by default; set to 0 to turn it off.
  • OMA_DYNAMIC_TOOLSOptional. Set to 1 to also expose one open_<name> tool per saved app. Off by default, because it costs prompt cache.

Environment variables as listed in the server's MCP Registry entry.
