Frequently asked questions
How do I get my Ugosign API Key?
Log in to your Ugosign account, navigate to the Developer API or Integrations section, and copy your secret Bearer Token.
Can I track the status of a specific signature request?
Yes, use the get_signature_request tool with the unique ID to see if it is 'pending', 'viewed', or 'signed'.
Does it support multiple recipients?
Absolutely. You can specify one or more recipients when creating a new signature request via the create_signature_request tool.
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.
