AI-native data catalog with search, lineage and MCP | Marmot

Hello everyone, I’m Charlie – I built Marmot because data catalogs solve a simple problem: What data do we have and where does it live? But most catalogs will ask you to run Elasticsearch, Kafka, and a graph database to find out. The data catalog shouldn’t require an entire platform team to run.
Now your AI agents need to answer these same questions – without valid context, they hallucinate. Marmot gives them a single source of truth to interrogate.

Marmot is a single binary and Postgres database that can be deployed in minutes. It currently contains:

  • 25+ plugins (and growing) including – DBT, Kafka, S3, Trino, Iceberg, PostgreSQL.

  • Complete data lineage across your business

  • Built-in MCP server to provide LLM context around your data

  • 100% free and open source.

Give it a try and let me know what you think!
