Package (npm 0.5.9)

npx -y @2nd1st/[email protected]

Or add to your MCP client config:

{
  "mcpServers": {
    "open-mcp-apps": {
      "command": "npx",
      "args": [
        "-y",
        "@2nd1st/[email protected]"
      ],
      "env": {
        "OMA_DB": "<YOUR_VALUE>",
        "OMA_VIEWER": "<YOUR_VALUE>",
        "OMA_DYNAMIC_TOOLS": "<YOUR_VALUE>"
      }
    }
  }
}

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