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 1476+ live data sources.
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.
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 1476+ data sources. The
only difference is which pack's tools are listed directly; ask_pipeworx
reaches all of them from either one.
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.
