Set up Claude Code Plugin with Remote MCP Private Preview

You can install the Atlan Claude Code Plugin from the Claude Code marketplace to connect to Atlan using OAuth authentication. No API keys or manual MCP configuration are required.

Once installed, sign in with your Atlan account to access the full suite of Atlan MCP tools. This is the recommended approach for a simple and streamlined setup experience.

Prerequisites​

Before you begin, make sure you have:

  • An Atlan tenant with Remote MCP enabled. If you don't have access, contact Atlan support or your Atlan customer team to request it.
  • Claude Code installed and available in your terminal.
  • Your Atlan credentials ready to complete the OAuth login.

Install Atlan plugin​

  1. In your terminal, start Claude Code by running:

    claude

  2. Open the plugin manager by typing:

    /plugin

  3. Press Tab to navigate to the Marketplace tab.

  4. Use the arrow keys to select claude-plugins-official and press Enter. Choose Update marketplace from the options that appear, then press Enter. This step pulls the latest plugin catalog from Anthropic's repository.

  5. Press Shift+Tab to go back to the Discover tab.

  6. Start typing atlan to filter the list. Select the atlan plugin using the arrow keys and press Enter.

  7. Choose an install scope and press Enter:

    • User: Available across all your projects. Recommended for most users.
    • Project: Shared with collaborators in the current project.
    • Local: Available only in this repository.

  8. Your browser opens the Atlan OAuth page. Sign in with your Atlan credentials. The terminal confirms the connection once authenticated.

  9. Reload plugins by running:

    /reload-plugins

  10. To verify the installation, run /plugin again, navigate to the Installed tab, and confirm atlan is listed and enabled.

You can now use Atlan MCP tools inside Claude Code.

Run from local clone​

To run the plugin from a local clone of the repository instead of the marketplace, use:

claude --plugin-dir ./claude-plugin

The plugin source is available at github.com/atlanhq/agent-toolkit.
