How do I obtain my HCSS API credentials?

You must request API access through the **HCSS Developer Portal** (developer.hcssapps.com). Once approved, you will receive your Client ID, Client Secret, and Ocp-Apim-Subscription-Key.

Can I see the real-time location of my equipment?

Yes! Use the `get_equipment_location` tool with the unique equipment ID. It will return the latest GPS coordinates recorded by the Telematics system.

Does this integration cover both HeavyJob and HeavyBid?

Yes, this MCP server includes tools for both modules, allowing you to access timecard data from HeavyJob and estimate/bid data from HeavyBid in a single interface.

Is the integration secure for construction data?

Absolutely. The integration uses industry-standard OAuth 2.0 Client Credentials flow and HTTPS. Your credentials are encrypted and stored securely within the Vinkius Cloud infrastructure.

HCSS + Google ADK FAQ

Common questions about integrating HCSS MCP Server with Google ADK.

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.
