Security Notes

The server demonstrates strong security practices including comprehensive input validation using Zod, server-side clamping of row limits, and configurable HTTP timeouts. The most sensitive tool, `datastore_search_sql`, is disabled by default (`ENABLE_SQL=false`) and includes basic regex guards against DDL/DML operations if enabled. No 'eval' or obfuscation found. Network calls are primarily to a configurable CKAN API base URL. The `fetchResource` utility, while capable of fetching arbitrary URLs, is not directly exposed as an MCP tool in the provided code, mitigating potential SSRF risks through that pathway.
