Open-source data catalog. Search assets, explore lineage, and find ownership.
Open-source data catalog. Search assets, explore lineage, and find ownership. That is what the marmot data catalog mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.
The open-source context layer for your AI. Catalog your tables, topics, queues and APIs then expose real metadata to your AI agents.
Marmot is an open-source data catalog for teams who want powerful data discovery without enterprise complexity. Catalog every data asset, enrich it with the context that matters and make it accessible to your team and your AI tools.
Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.
The server publishes 8 tools. What each one is for:
Metadata-first — Store rich metadata for any asset type, from tables and topics to APIs and dashboardsAI-ready — Expose certified context through MCP, the API and the UIFeature — BenefitMetadata-First — Store rich metadata for any asset type (tables, topics, APIs, dashboards)AI-Ready — Expose certified context through MCP, API, and UIMethod — DescriptionResource — LinkDocumentation — marmotdata.io/docsPlenty of knowledge and memory servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Marmot Data Catalog's toolset — Metadata-first, AI-ready, Feature and 5 more — is a fair guide to whether it matches your workflow. It is maintained by marmotdata; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

A knowledge graph your assistant keeps between sessions — entities, relations and observations that persist.
Kill hallucinated APIs — version-accurate, up-to-date library documentation injected straight into context.
Your workspace, on speaking terms with AI — search, read and write Notion pages and databases.
A structured scratchpad for hard problems — stepwise reasoning with revisions, branches and visible logic.
Symbol-level code navigation, refactoring and memory for coding agents — the IDE brain your assistant has been missing.
Chat with your second brain — search, read and write vault notes through the Local REST API.
