Provides a bridge to the Unleash feature flag management system, enabling dynamic creation, retrieval, and management of feature flags across different development projects.
  1. Obtain Your Unleash Instance URL

    • Log into your Unleash admin interface or check your Unleash server deployment.
    • Copy the URL of your Unleash API endpoint (e.g., https://your-unleash-instance/api).
  2. Generate or Locate Your Unleash API Token

    • In the Unleash admin interface, click on “API access” or look for a “Tokens” section (this may depend on your Unleash version).
    • Click “Create API token” or locate an existing one with the necessary permissions.
    • Set the token type (typically “Client” or “Admin” as required for your integration) and define the token scope if prompted.
    • Copy the generated token. Note: API tokens are usually shown only once—save it securely.
  3. Fill In FastMCP Connection Interface

    • Click the “Install Now” button in your FastMCP integration flow.
    • When prompted, paste your Unleash API URL into the UNLEASH_API_URL field.
    • Paste your Unleash API token into the UNLEASH_AUTH_TOKEN field.
    • Confirm/save the connection.

Now the Unleash Feature Flag MCP Server can manage feature flags using your Unleash instance via FastMCP.
