Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@us-open-stats-mcp What's the current unemployment rate in California?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.

Default responses use recorded fixtures so CI stays offline. For live HUD FMR set HUD_API_TOKEN (optional). Every MCP snapshot includes license_note, vintage, source_url, and retrieved_at.
Live API keys can be added later without changing tool names. FRED tools remain fixture-oriented (see FRED API terms before redistributing live series).

Scored across 5 tools
Most tools target distinct metrics (population, rent, unemployment, CPI), but get_fred_series is a generic catch-all that can fetch the same BLS/CPI series as the specialized tools, creating overlap and potential misselection.
All tools follow a consistent get_<metric> snake_case pattern, making the naming predictable and easy to parse.
Five tools is well-scoped for a focused statistical data server; each tool earns its place without bloat or extreme thinness.
Core economic indicators (population, rent, unemployment, CPI, generic FRED) are covered, but there is no way to list available series, sources, or metadata, which limits discoverability.
Fetch US Bureau of Labor Statistics data — CPI, unemployment, wages, JOLTS, and more via MCP.
