This one needs environment variables set before it will start:
SOCRATA_APP_TOKEN (Socrata app token (X-App-Token header). Without a token, requests share a throttled pool per source IP. Free to register at any Socrata portal.), SOCRATA_DEFAULT_DOMAIN (Default portal domain when domain is omitted from tool calls (e.g. data.seattle.gov, data.cityofnewyork.us).), MCP_HTTP_HOST (The hostname for the HTTP server.), MCP_HTTP_PORT (The port to run the HTTP server on.), MCP_HTTP_ENDPOINT_PATH (The endpoint path for the MCP server.), MCP_AUTH_MODE (Authentication mode to use: 'none', 'jwt', or 'oauth'.), MCP_LOG_LEVEL (Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').).
The author declared them in the registry entry; get the values from the project itself.
