@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 1689+ 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

• PSD API: https://api.fas.usda.gov/api/psd

• Key signup: https://apps.fas.usda.gov/opendataweb/

Quick Start

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

{
  "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:

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

Both URLs reach the same gateway and the same 1689+ 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

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":"..."}.

Standalone (no gateway account)

This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:

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

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-fas

It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call for only this pack's tools — none of the shared meta-tools the gateway connection above adds. Same source, same tools, no ask_pipeworx routing.

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:

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

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