# pipeworx `comtrade` — Comtrade

## Coverage
UN Comtrade API for international bilateral trade data.

Catalog `tool_count`: 4. Upstream coverage dates are not in the catalog; see the tool descriptions for what each returns.

## Access
MCP endpoint `https://gateway.pipeworx.io/comtrade/mcp` — JSON-RPC `tools/list` and `tools/call` over POST, SSE-framed response (`event: message`, one `data:` line; the answer is in `result.structuredContent`). `tools/list` on 2026-10-01 returned 40 tools: these 4 plus the 36 platform tools every pack endpoint lists.

Tools (names and first sentence of each description as served on 2026-10-01):

- `comtrade_trade_data` — AUTHORITATIVE bilateral trade data between two countries from UN Comtrade — the official international-trade statistics database (every country's customs filings, harmonized). Required: `reporter_code`, `partner_code`, `year`.
- `comtrade_top_partners` — Find a country's top trading partners ranked by trade volume. Required: `reporter_code`, `year`, `flow`.
- `comtrade_top_commodities` — Rank the products two countries actually trade, largest value first — "what does the US import most from China". Required: `reporter_code`, `year`, `flow`.
- `comtrade_country_codes` — Look up UN Comtrade reporter/partner codes for trade queries (e.g., "842" = US, "156" = China). No required arguments.

Client setup: `claude mcp add pipeworx-comtrade -- npx -y mcp-remote https://gateway.pipeworx.io/comtrade/mcp`.

## Auth
Catalog `auth.shape`: `keyless`. Verbatim detail: "No key required — open upstream, callable as-is." No credential is needed at the gateway to list or call (anonymous tier; see the gateway record).

## Rate limits
Gateway anonymous tier: 50 calls per day per IP, reset 00:00 UTC, printed in `x-ratelimit-*` headers (observed 2026-10-01 on the fred and weather packs; this pack was listed, not called). Upstream limits are not stated in the catalog.

## Freshness
Not stated in the catalog. Reliability: not measured — catalog says treat as unknown, not good.

## Known gaps
- Cost per call as quoted: 50 credits ($0.0050), category `gov`, basis `list`.
- No catalog notes on cost or licence.
- This record is the catalog's description plus one `tools/list`; it is not a test of the upstream data. Reuse it to find the tool, then observe the upstream yourself.

History

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
