The atlanai plugin connects your coding agent to Atlan Trident. It adds one MCP server, atlan, at https://api.atlan.com/mcp, and the atlan-* skills that teach the agent to find, use and publish your organization’s skills, agents, knowledge and MCP servers. You sign in once through your browser; there is no API key. The plugin is published from the atlanai/atlan-plugins marketplace, named atlan. The same marketplace offers atlanai-analytics, which builds on it: see Set up Analytics in your coding agent.
Installing the plugin does not capture your sessions. To record coding-agent sessions as traces, see Capture coding-agent traces with aireg.

Before you start

  • An account in an Atlan organization that can sign in through the browser.
  • On Claude Team and Enterprise plans, an Owner first adds the connector https://api.atlan.com/mcp for the organization.

Install plugin

Inside a running Claude Code session, type the install as /plugin install …, then /reload-plugins.

Sign in

Verify installation

Ask your agent “Connect me to Atlan.” In Claude Code, /atlanai:get-started does the same. The agent checks the sign-in and shows what your organization has.

Updates

Each tool updates the plugin from the marketplace on its own refresh. Claude Code keeps the version you installed until the marketplace’s auto-update is on; the Atlan desktop app turns it on when it installs the plugin. In Codex, run codex plugin marketplace upgrade atlan. To take a fix now in Claude Code, run claude plugin marketplace update atlan, then claude plugin update atlanai@atlan (and atlanai-analytics@atlan if you use Analytics). In any other agent, run the install step again, or npx plugins add atlanai/atlan-plugins for every agent at once. You don’t need to sign in again. A running session keeps the version it started with. Type /reload-plugins in Claude Code, or restart VS Code, before you check whether a fix worked.

Troubleshooting

  • The Atlan tools are about search, lineage and glossaries. That is the atlan plugin from Anthropic’s directory, Atlan’s data catalog plugin. Install atlanai beside it.
  • Atlan skills appear twice. The plugin is installed from two marketplaces, or the atlan server was also added by hand. Keep one.
  • A call is refused or fails. Ask your agent to use atlan-troubleshoot.
