The atlan plugin is the official Claude Code plugin for Atlan, enabling users to search, explore, govern, and manage data assets through natural language via the hosted Atlan MCP server at mcp.atlan.com/mcp. According to the README, it connects via OAuth with no API keys required and provides 15 MCP tools, 12 enabled by default and 3 available via feature flags. Its capabilities span semantic search, lineage tracing, governance (glossaries, terms, certifications), data quality rule creation and scheduling, and data mesh organization of domains and data products. The README also notes that the local Atlan MCP server in the same repository is deprecated in favor of this hosted endpoint.

Overview

According to the Atlan homepage, Atlan is described as 'the context layer for AI,' a platform for connecting an organization's data estate, capturing business knowledge, and making it available to the AI tools it runs. It includes components such as Connectors, Lakehouse, Lineage, Discovery, Contracts & Policies, Glossary, Atlan AI, Context Agents Studio, and an MCP Server for connecting to Claude and other AI agents.
