This MCP server implementation provides a bridge to DataHub, a metadata platform for data ecosystems. Developed by Acryl Data, it integrates with the DataHub API to offer tools for entity retrieval and search functionality across various data assets. The server is designed for use cases requiring metadata management and discovery in complex data environments, such as data cataloging, lineage tracking, and governance.
