Frequently asked questions
Can my AI automatically find the status for a specific transaction by its ID?
Yes! Use the get_transaction tool with the Transaction ID. Your agent will respond with complete metadata, including payment method, currency, amount, and final status in seconds.
How do I find my Payrexx API Secret and Instance Name?
Log in to your Payrexx merchant dashboard, navigate to Settings > API, and you will find your unique secret key and instance name (e.g., yourname.payrexx.com) there.
Does this work for recurring payments?
Absolutely. You can use the list_subscriptions tool to monitor active recurring billing cycles and orchestrate multi-use gateways for recurring customer payments.
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.
