Why does it require an API key?

While the SEC and Treasury APIs do not require keys, the Census Bureau requires a free API key to handle the massive volume of hyper-local data (thousands of variables across millions of geographies). The key prevents rate limiting and ensures stable connections.

What geographies can I query?

This MCP limits the main built-in endpoints to State, County and Place (cities). Detailed geometries like zip-codes, tracts, or congressional districts can be queried utilizing the `query_census` custom tool.

Is Puerto Rico included?

Yes! Puerto Rico is treated internally as state FIPS code `72`.

U.S. Census Full — Complete Demographic & Economic Intelligence + Claude Desktop FAQ

Common questions about integrating U.S. Census Full — Complete Demographic & Economic Intelligence MCP Server with Claude Desktop.

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.
