This one needs environment variables set before it will start: MCP_TRANSPORT (Transport mode selection), MCP_HTTP_PORT (HTTP server port (when using HTTP transport)), MCP_HTTP_HOST (HTTP server host (when using HTTP transport)), ES_URL (Your Elasticsearch instance URL (e.g., https://localhost:9200)), ES_API_KEY (Elasticsearch API key for authentication), ES_USERNAME (Elasticsearch username for basic authentication), ES_PASSWORD (Elasticsearch password for basic authentication), ES_CA_CERT (Path to custom CA certificate for Elasticsearch SSL/TLS), NODE_TLS_REJECT_UNAUTHORIZED (Set to '0' to disable SSL certificate validation (development only)), MAX_TOKEN_CALL (Maximum tokens per API call). The author declared them in the registry entry; get the values from the project itself.
