Frequently asked questions
Do I need an API key to use this server?
No. The CMS.gov Provider Data API is completely public and requires no authentication. Simply subscribe to this server to start querying Medicare provider data, hospital ratings, and open datasets immediately.
How current is the data?
CMS updates the Provider Data Catalog periodically, typically on a quarterly or monthly basis depending on the dataset. Hospital quality ratings are updated annually through the Hospital Compare program. All data is sourced directly from the official CMS.gov open data APIs.
What is an NPI number?
The National Provider Identifier (NPI) is a unique 10-digit identification number issued by CMS to every US healthcare provider. It's the universal standard for identifying doctors, hospitals, and healthcare organizations in Medicare and Medicaid transactions. You can search for any provider by their NPI using this server.
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.
Server not appearing after restart
Ensure the JSON is valid (no trailing commas). Check the file path: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\\Claude\\ (Windows).
Authentication error
Verify your Vinkius token is correct. Go to cloud.vinkius.com to regenerate it if needed.
Tools not showing in chat
Click the 🔌 icon at the bottom of the chat input. If it shows 0 tools, the server may still be connecting. wait a few seconds.
