Atlan Agent Toolkit

[!WARNING] The local Atlan MCP server in this repository is deprecated. Use the hosted Atlan MCP at mcp.atlan.com/mcp instead.

The local install path (cloning this repo or pip install atlan-mcp-server) is in maintenance-only mode — no new features, support not guaranteed. The hosted endpoint is the recommended way to integrate Atlan with Claude Desktop, Cursor, Codex, Databricks UC, and other MCP clients.

See the Atlan MCP overview for migration instructions.

This repository contains a collection of tools and protocols for interacting with Atlan services for AI agents. Each component is designed to provide specific functionality and can be used independently or together.

Components

Model Context Protocol (MCP)

An MCP server that enables interaction with Atlan services through tool calling. Provides tools for asset search, and retrieval using pyatlan.

You can find the documentation and setup instructions for the MCP server here.

Claude Code Plugin

The official Atlan plugin for Claude Code. Search, explore, govern, and manage your data assets through natural language, powered by the Atlan MCP server.

Connects to Atlan via OAuth at mcp.atlan.com/mcp - no API keys required.

Features:

• 15 MCP tools (12 enabled by default, 3 via feature flags)
• Search: AI-powered semantic search across data assets
• Lineage: Trace data flow upstream and downstream
• Governance: Manage glossaries, terms, certifications
• Data Quality: Create and schedule validation rules
• Data Mesh: Organize domains and data products

Setup:

# Install from marketplace (when available)
/plugin marketplace add atlanhq/agent-toolkit
/plugin install atlan@atlan-marketplace

# Or test locally
claude --plugin-dir ./claude-plugin

For detailed plugin documentation, see claude-plugin/README.md.

Skills

skills/ holds the agent skills both plugins ship. A skill is instructions, not code: it teaches the agent how to use the tool surface well, and loads only when the task calls for it.

Skill	What it covers
atlan-search	Which discovery tool to reach for, and the filter rules that make each one return the right answer — types, tags, custom metadata, owners, glossary, domains and products, data quality, lineage, BI and pipelines, counts and breakdowns

Both plugins read the same directory (cursor-plugin/skills is a symlink), so a skill is authored once and shipped to Claude Code and Cursor together.

Skills are measured, not assumed: the golden-eval harness runs the same dataset with and without them and diffs the scorecard per case. Adding or editing a skill means running that A/B and quoting the delta.
