Frequently asked questions
Can I search for a client by their email address?
Yes! Use the list_crm_clients tool and provide the optional email parameter. The agent will return the specific record for that client if it exists in your CRM.
How do I book a new service for an existing client?
Use the create_new_booking action. You'll need to provide the Client ID, the Service ID, and the start time in ISO 8601 format (e.g., 2024-12-01T10:00:00Z).
Is it possible to list all unpaid invoices via AI?
Absolutely. Use the list_client_invoices query. The agent will retrieve all your billing documents, and you can then ask the AI to filter or identify those with a 'pending' or 'overdue' status.
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.
