Connects Claude to USAspending.gov's federal spending database through a streamable HTTP gateway. Part of the Pipeworx platform, which bundles 673+ data sources behind a single MCP endpoint. The interesting bit is the ask_pipeworx tool that lets you query in plain English instead of calling specific API methods directly. Useful when you're analyzing government contracts, tracking agency budgets, or need to answer questions about where federal dollars are going without manually constructing API calls. You can install just the USAspending endpoint or connect to the full Pipeworx gateway for broader data access. Hosted service, so no local setup required.
The U.S. Treasury's USAspending.gov data on federal awards: contracts, grants, loans, and direct payments. Every dollar the federal government has awarded since 2008 (with patchier coverage going back to 2001), broken down by recipient, agency, sub-agency, NAICS code, and place of performance. Free, no auth.
Part of Pipeworx — an MCP gateway connecting AI agents to 1815+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.
Where SAM.gov is opportunities (what the government is buying), USAspending is awards (what was actually contracted). For competitive intelligence, lobbying-spend ROI analysis, federal vendor research, or following the money on policy areas, this is the source of truth.
Common flows:
get_federal_spending({recipient: "X"}) → award totals by year, agency.Used by the govcon_contractor_profile and lobbying_activity recipes.
None. USAspending is fully public, free.
| Class | What it is |
|---|---|
| Contracts (FPDS-NG) | Direct procurement; competitive or sole-source |
| Grants | Discretionary or formula awards (research, state grants) |
| Loans | Federal credit programs (SBA, USDA, Education) |
| Direct payments | Social Security, veterans benefits, etc. |
| IDV (Indefinite Delivery Vehicles) | Master contracts; orders flow against them |
For company-level analysis, contracts are usually what matters. Grants matter for universities and nonprofits.
usa_expiring_awards / usa_incumbent_profile"Which VA IT contracts over $10M expire in the next 12 months, and who holds them" is the core govcon business-development question, and these two tools answer it directly — no key, no upstream throttle.
usa_expiring_awards({agency: "Department of Veterans Affairs", naics: "5415",
min_amount: 10000000, months_ahead: 12})
usa_incumbent_profile({recipient: "Booz Allen"})
usa_expiring_awards returns the incumbent, period of performance, obligated
dollars, agency/sub-agency, NAICS/PSC and a usaspending.gov link per award.
usa_incumbent_profile returns one contractor's portfolio: active awards, total
obligated, ceiling, expirations at 6/12/18 months, top agencies and NAICS.
These read usaspending_awards_current, a materialized view of one row per
award (626,306 awards from 1,510,983 transactions). Rebuild it after every
pipeline load with select usaspending_refresh_awards_current(); — it also
restamps the mirror_as_of that every response carries.
Grain. The base table is one row per transaction. Every modification
repeats the award's PIID, so querying usaspending_contracts directly counts
one contract many times and sums its money just as often. Use the view.
Two different end dates. period_of_performance_current_end_date is the
recompete decision point. period_of_performance_potential_end_date is when
all options would be exhausted. An award ending in 6 months whose options run
3 more years will be extended, not recompeted — listing it as a lead is a
false positive that looks exactly like a real one. options_status reports
options_remain / no_options_remain / unknown, and it is unknown
for everything loaded before 2026-08-28: the potential end date was dropped at
ingest and only starts populating on the next pipeline run.
The end date is the latest transaction's, not the maximum. 5,299 awards
(0.88%) disagree between the two, because a later modification can shorten
the period. Checked against api.usaspending.gov, latest-transaction matched
upstream 5 times out of 6 and max matched once. Don't "fix" it to max().
The date can still be stale. A modification filed after mirror_as_of may
have extended an award listed here as expiring — one $1.4B VA award read 14
months early for that reason. The usaspending_url is the live check.
IDVs are excluded. They are ordering vehicles with no period of performance, so they have no expiry. 443,315 transactions carry no end date, but only 22,221 of 626,306 awards lack one, because the date is taken from the latest transaction that actually has one.
min_amount filters obligated dollars, not the ceiling. A lightly-used
vehicle with a $40M ceiling and $40k of real work does not pass a $10M floor.
mirror_as_of comes from the data, not the snapshot filename. Those have
disagreed: the pinned snapshot URL read contracts-all-20260506.zip while the
table held action dates through 2026-08-04.
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"usaspending": {
"url": "https://gateway.pipeworx.io/usaspending/mcp"
}
}
}
tools/list at https://gateway.pipeworx.io/usaspending/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 1815+ data sources. The
only difference is which pack's tools are listed directly; ask_pipeworx
reaches all of them from either one.
curl -X POST https://gateway.pipeworx.io/v1/tools/usa_spending_by_agency \
-H 'Content-Type: application/json' \
-d '{"fiscal_year":"2024"}'
No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/usa_spending_by_agency. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.
This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:
{
"mcpServers": {
"usaspending": {
"command": "npx",
"args": ["-y", "@pipeworx/mcp-usaspending"]
}
}
}
Or run it directly to confirm it starts:
npx -y @pipeworx/mcp-usaspending
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.
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 Usaspending data" })
The gateway picks the right tool and fills the arguments automatically.
