Who it is for
Data platform and governance teams running Atlan as their metadata layer.
Overview
Atlan holds an organisation's metadata: data assets, business glossaries, semantic definitions, and the lineage that links them. The app connects that repository to ChatGPT so replies can be grounded in company definitions instead of general knowledge.
Its agent skills cover searching and discovering context, following lineage from source through to consumption, reading governed definitions and glossary terms, running SQL, curating the metadata graph, and checking data quality.
The example given in the record is a search for verified Snowflake tables, which shows the pattern it expects: filter catalog assets by governance status, not by name alone.
Data platform and governance teams running Atlan as their metadata layer.
It combines catalog search with SQL execution and lineage traversal in one connection.
Availability
Atlan is listed in the ChatGPT apps directory only. Atlan has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

This is an independent catalogue entry compiled by Node8 from Atlan's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with Atlan, and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
