Summary
Connects Claude to your Marmot data catalog instance via streamable HTTP, letting the AI search across tables, topics, queues, and APIs cataloged in your system. Useful when you want Claude to answer questions about what data assets exist, trace lineage between datasets, or look up ownership and documentation without leaving the conversation. Since Marmot stores rich metadata and runs as a single binary, this works well for teams who've already deployed it and want their AI to reference the same catalog humans use. Point it at your Marmot instance and Claude can query the same search, lineage, and ownership APIs exposed through the v1 MCP endpoint.

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.
Why Use Marmot?
| Feature | Benefit |
|---|---|
| Search Everything | Find any data asset in seconds with full-text search, structured queries, boolean logic, and metadata filters |
| Interactive Lineage | Trace data flows from source to destination, analyze impact before making changes |
| Metadata-First | Store rich metadata for any asset type (tables, topics, APIs, dashboards) |
| Team Collaboration | Assign ownership, document business context, maintain shared glossaries |
| AI-Ready | Expose certified context through MCP, API, and 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)
