Mcp Datahub
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.
