# pipeworx `usaspending` — Usaspending

## Coverage
Federal spending data from USAspending.gov API.

Catalog `tool_count`: 7. Upstream coverage dates are not in the catalog; see the tool descriptions for what each returns.

## Access
MCP endpoint `https://gateway.pipeworx.io/usaspending/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 43 tools: these 7 plus the 36 platform tools every pack endpoint lists.

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

- `usa_spending_by_agency` — Break down US federal contract spending by agency for a given fiscal year (default: current year) and optional quarter (1-4). No required arguments.
- `usa_award_search` — Search US federal PROCUREMENT CONTRACTS / government contract awards for goods and services. No required arguments.
- `usa_spending_by_category` — Analyze federal spending by industry, product/service, recipient, or agency. Required: `category`, `start_date`, `end_date`.
- `usa_recipient_profile` — Answer "what federal contracts did [company] win recently?" and get a contractor's federal contract awards. Required: `recipient_name`.
- `usa_spending_trends` — "How has [agency] contract spending trended over the last N fiscal years?" / "is [agency] spending on X growing?" / "federal spending history for [topic]" — US FEDERAL contract/award spending over time from USAspending.… No required arguments.
- `usa_expiring_awards` — Federal contracts EXPIRING soon -- the recompete calendar. No required arguments.
- `usa_incumbent_profile` — Federal contract portfolio for one contractor -- "what does Leidos hold and when does it expire", "which of Booz Allen's contracts come up for recompete", incumbent research before a bid. Required: `recipient`.

Client setup: `claude mcp add pipeworx-usaspending -- npx -y mcp-remote https://gateway.pipeworx.io/usaspending/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: 100 credits ($0.0100), category `exclusive`, 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.

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.
