FAQ

Frequently asked questions

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.

How does Claude Desktop discover MCP tools?

When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.

What happens if the MCP server is temporarily unavailable?

Claude Desktop handles disconnections gracefully. if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.

Can I connect multiple MCP servers simultaneously?

Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.

Is there a limit on the number of tools per server?

Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.

Does Claude Desktop support Streamable HTTP transport?

Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL. Claude auto-negotiates the transport protocol.
