Add to Claude Desktop

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "romm": {
      "command": "python",
      "args": ["/path/to/mcp-romm/server.py"],
      "env": {
        "ROMM_URL": "http://your-romm-instance:3000",

Examples

Once configured, you can ask your AI assistant things like:

"What platforms do I have in RomM?"
"Search for Zelda games"
"Show me my backlog"
"How many ROMs do I have total?"
"What was recently added?"
"Show me the saves for Super Metroid"
"What's in my favorites?"
"List my firmware files for PlayStation"
"What tasks are running?"
"What devices are registered?"

Security

Read-only. All 19 tools are read-only. The only mutation is romm_scan_library, which triggers an idempotent library rescan.
No disk writes. Credentials and tokens are held in memory only, never written to disk.
Scoped tokens. OAuth2 tokens request only the scopes needed for read operations.
TLS by default. Certificate verification is enabled by default (ROMM_TLS_VERIFY=true).
Auto-retry. If a token expires mid-session, the server re-authenticates transparently.

Auth

The server uses OAuth2 password grant to authenticate with RomM. Tokens are scoped to the minimum permissions needed and automatically refreshed when they expire. If a request gets a 401, the server re-authenticates and retries once.

Note: Your RomM user must have the admin role for all tools to work. The user must also be enabled in the RomM admin panel.
