Connects Claude to DataHub's GraphQL API for metadata discovery and lineage exploration. Exposes 12 tools covering search, schema inspection, glossary terms, domains, and data lineage tracing. Ships as both a standalone MCP server and a composable Go library, so you can embed it in custom servers with your own auth and tenant logic. Built to work alongside mcp-trino and mcp-s3 for a full data platform stack. Supports multi-instance connections if you run staging and production DataHub clusters. The library includes a QueryProvider interface that lets query engines inject execution context back into metadata responses, turning URNs into queryable table identifiers with sample SQL.
