@pipeworx/fas

USDA Foreign Agricultural Service MCP — global production, supply and distribution (PSD) estimates by commodity and country.

Part of Pipeworx — an MCP gateway connecting AI agents to 1864+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

  • fas_production(commodity, country?, market_year?) — PSD rows (production, consumption, stocks, trade totals) for a commodity, world-wide or for one country. Accepts a commodity name ("corn") or PSD code ("0440000"); walks back up to two market years when the current one is not yet published.
  • fas_commodity_codes(category?, search?) — the bundled list of PSD commodity codes and common country codes.

Agricultural trade (exports / imports)

fas_exports and fas_imports were removed on 2026-10-06 (fleet #2704). They never returned data — every call answered "use comtrade". For US or global agricultural trade by commodity and partner, call the keyless comtrade pack: comtrade_trade_data, comtrade_top_partners, comtrade_top_commodities.

Auth

Platform key. FAS OpenData sits on the api.data.gov umbrella and now requires a key; the gateway injects the shared data.gov platform key. A caller may pass their own as _apiKey. With no key, fas_production returns api_key_required with the signup link instead of failing.

Data sources

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

config.json
{
  "mcpServers": {
    "fas": {
      "url": "https://gateway.pipeworx.io/fas/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/fas/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

config.json
{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1864+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

Terminal
curl -X POST https://gateway.pipeworx.io/v1/tools/fas_production \
  -H 'Content-Type: application/json' \
  -d '{"commodity":"corn","country":"US","market_year":"2024"}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/fas_production. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Run it from npm

@pipeworx/mcp-fas is a local stdio bridge to the Pipeworx gateway: your MCP client starts it with npx, and it forwards every call to the same https://gateway.pipeworx.io/fas/mcp endpoint shown above. It needs network access; there is no offline mode.

config.json
{
  "mcpServers": {
    "fas": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-fas"]
    }
  }
}

Without a key it calls anonymously, capped at 50 calls a day. A free account raises that to 200 a day: get a key at https://pipeworx.io/signup and add "env": { "PIPEWORX_API_KEY": "<your key>" } to the server entry. The key is sent as a Bearer token, the same way a hosted connection sends it, so calls are metered and billed exactly as they are there.

It lists only this pack's tools by default. Set PIPEWORX_META_TOOLS=1 to also list ask_pipeworx and the other gateway-wide tools.

Behind an HTTPS proxy: Node's built-in fetch does not read HTTPS_PROXY by default. Newer Node releases honour it when NODE_USE_ENV_PROXY=1 is set; check your Node version's documentation.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

Code
ask_pipeworx({ question: "your question about Fas data" })

The gateway picks the right tool and fills the arguments automatically.
