Integrates with Argo CD to enable natural language management of Kubernetes GitOps applications, resources, and deployments without switching context from your assistant.
  1. Log in to your Argo CD Web UI

    • Open your Argo CD instance in a browser. The URL will look like https://<ARGOCD_BASE_URL>/.
  2. Navigate to "Settings" → "Accounts" or "User Info"

    • Once logged in, locate either the user dropdown menu or the “Settings”/“Accounts” section, depending on your Argo CD version and how authentication is configured.
  3. Generate an API Token

    • If using the built-in admin account:
      1. Go to “Settings” (gear icon) > “Accounts”.
      2. Find the desired account (commonly “admin”).
      3. Click “Generate Token” or the equivalent action.
    • If using Single Sign-On or another account:
      1. Click your user avatar or name at the top right.
      2. Choose “Generate API Token” or open “User Info” > “Create Token”.
  4. Copy the API Token

    • Copy the generated API token (“ARGOCD_API_TOKEN”).
    • You’ll need this for secure MCP server access.
  5. Find Your Argo CD Base URL

    • Your base URL is typically the address you used to access the Argo CD UI—e.g., https://argocd.example.com.
    • This will be the value for “ARGOCD_BASE_URL”.
  6. Open the FastMCP Connection Interface

    • Click the "Install Now" button or otherwise access the MCP server connection dialog in your tool (e.g., VS Code, Cursor, etc.).
  7. Fill in the Environment Values

    • In the FastMCP connection interface, enter:
      • ARGOCD_BASE_URL: The Argo CD server URL (e.g., https://argocd.example.com)
      • ARGOCD_API_TOKEN: The API token you generated earlier
  8. (Optional) For Self-Signed Certificates

    • If your server uses a self-signed certificate, add:
      • NODE_TLS_REJECT_UNAUTHORIZED with a value of 0 (use only if you understand the security implications).
  9. Save and Connect

    • Finalize the setup and save your configuration in the FastMCP interface.

You can now interact with your Argo CD instance using your MCP client!
