This one needs environment variables set before it will start: HOST (Interface to bind to), PORT (Port to listen on), MCP_WORKSPACE_DIR (Directory that read_file/write_file/list_dir are restricted to), AUTH0_DOMAIN (Auth0 tenant domain, e.g. your-tenant.eu.auth0.com), AUTH0_CLIENT_ID (Auth0 application client ID), AUTH0_CLIENT_SECRET (Auth0 application client secret), AUTH0_AUDIENCE (Auth0 API audience/identifier), ALLOW_INSECURE_NO_AUTH (Set to true only for local-only testing without Auth0). The author declared them in the registry entry; get the values from the project itself.
