Marmot Data Catalog

Marmot Data Catalog is an open-source MCP (Model Context Protocol) server that exposes a searchable catalog of data assets—including tables, queues, APIs, and more—to both AI assistants and human users. It provides powerful data discovery, interactive lineage tracing, rich metadata storage, and collaborative ownership/documentation tools, all deployable with minimal infrastructure. Marmot is designed for data engineering teams and organizations who need an accessible and centralized data catalog, with direct integration to AI systems via MCP to power context-aware AI workflows, discovery, and governance.
