Frequently asked questions
How do I find my Highnote API Key?
Log in to your Highnote dashboard, navigate to Settings > API, and you will be able to generate and copy your API key. Make sure to distinguish between Test and Live keys based on your environment.
What environments are supported?
The integration supports both the Test (Sandbox) and Live (Production) environments. You must specify which one you are connecting to during setup to ensure the correct API endpoints are used.
Can I freeze a card through this integration?
Yes! Use the update_card_status tool and set the status to FROZEN. This will immediately prevent any new authorizations on that card. You can set it back to ACTIVE to unfreeze it.
Is the integration secure for financial data?
Absolutely. The integration uses industry-standard Basic Authentication over HTTPS. Your credentials and financial data are encrypted and stored securely within the Vinkius Cloud infrastructure.
How does Google ADK connect to MCP servers?
Import the MCP toolset class and pass the server URL. ADK discovers and registers all tools automatically, making them available to your agent's tool-use loop.
Can ADK agents use multiple MCP servers?
Yes. Declare multiple MCP tool providers in your agent configuration. ADK merges all tool schemas and the agent can call tools from any server in a single turn.
Which Gemini models work best with MCP tools?
Gemini 2.0 Flash and Pro models both support function calling required for MCP tools. Flash is recommended for latency-sensitive use cases, Pro for complex reasoning.
