FAQ

What is Marmot?

Marmot is an open-source data catalog for teams who want powerful data discovery without enterprise complexity. It catalogs every data asset (tables, topics, queues, APIs), enriches it with context, and makes it accessible to both your team and AI tools. Unlike traditional catalogs requiring extensive infrastructure, Marmot ships as a single binary with an intuitive UI.

How Does Marmot Integrate with AI Agents?

Marmot exposes certified context through MCP (Model Context Protocol), enabling AI agents to query real metadata about your data assets. This allows AI tools to understand your data landscape, trace lineage, and make informed decisions based on actual metadata rather than guessing.

What Data Sources Can I Catalog?

Marmot supports cataloging various data asset types through its plugin system:

  • Tables (databases, data warehouses)
  • Topics (message queues, event streams)
  • Queues (job queues, messaging systems)
  • APIs (REST, GraphQL, internal services)
  • Dashboards (visualization tools, BI platforms)
