Connects Claude to SAM.gov, the federal government's contract opportunities and entity registration system. This is a Pipeworx gateway integration, so instead of wrestling with individual tool calls, you use ask_pipeworx with plain English questions about federal contracts, vendor registrations, or procurement data. The gateway handles tool selection and parameter mapping automatically. Useful if you're tracking government RFPs, researching contractors, or building workflows around federal procurement. Part of a larger 250-source gateway, but you can connect to just the SAM.gov endpoint if that's all you need. Runs over streamable HTTP.
The U.S. General Services Administration's System for Award Management. The authoritative source for federal contract opportunities, entity (vendor) registrations, set-aside designations, exclusion records (debarments), and assistance listings. Required reading for anyone selling to the federal government.
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.
Three distinct surfaces:
1. Contract opportunities (RFPs, RFQs, sources sought, etc.) — what the federal government is currently buying. → sam_search_opportunities({keyword}). For one specific solicitation: sam_get_opportunity({solicitation_number}).
2. Entity records — registered vendors with CAGE codes, UEIs, NAICS codes, certifications. → sam_entity_search({business_name}).
3. Set-aside opportunities — small business, veteran-owned, women-owned, HUBZone, etc. → sam_set_aside_opportunities({set_aside}).
Pair with USAspending (post-award contract data) and the govcon_contractor_profile compound for full agent flows.
SAM.gov requires a free API key from https://sam.gov/data-services. Pass via _apiKey. The shared PLATFORM_SAM_KEY the gateway falls back to when a caller supplies none is a personal-tier key with a hard 10-request DAILY quota — measured live 2026-09-01: it answered exactly ten calls and returned 900804 Message throttled out for the rest of the UTC day, with nextAccessTime set to the next midnight UTC. See the mirror note below for why sam_search_opportunities mostly doesn't need it anymore. Entity search and exclusion search no longer need a key either (migration 135): both answer from local snapshots of SAM.gov's public Entity Registration and Exclusions extracts. Verified live 2026-09-13 with no key supplied — sam_entity_search returned Lockheed Martin from an 889,932-row mirror and sam_search_exclusions answered from a 168,462-row one. Only sam_get_opportunity and sam_set_aside_opportunities still hit the live, key-gated API on every call; sam_entity_search also does when you pass live:true.
A key of your own is worth bringing. GSA sets the quota by what the ACCOUNT carries, not by what you pay: a non-federal personal key with no SAM.gov role gets 10/day (that is the tier the shared key sits on), the same key gets 1,000/day once the account carries a role, and a non-federal system account also gets 1,000/day — all free (https://open.gsa.gov/api/entity-api/). So passing _apiKey is not a workaround for a Pipeworx limit, it is a 100x larger allowance for a profile change.
When the shared key is spent, these tools do not return a bare upstream error: they say the quota is a daily one, quote the exact reset instant SAM.gov reported, and name both remedies (_apiKey, or sam_search_opportunities, which answers keyword searches with no key at all). A daily quota cannot be retried out of, and an agent that is not told so will keep trying.
sam_search_opportunities reads a Supabase mirror first, before ever spending the shared API key: SAM.gov publishes the entire Contract Opportunities list as a public daily CSV extract, no key and no rate limit — https://s3.amazonaws.com/falextracts/Contract%20Opportunities/datagov/ContractOpportunitiesFullCSV.csv (the same falextracts bucket linked from SAM.gov's own Data Services page). A GitHub Actions job (scripts/samgov-upsert.sh, schedule in .github/workflows/samgov-refresh.yml) loads it into samgov_opportunities daily.
The mirror ranks matches by relevance (rpc/search_samgov_opportunities, migration 075) rather than a plain title-or-description filter: title is weighted well above description (setweight() + ts_rank_cd). Two earlier cuts got this wrong, both caught live: a plain description match on "cybersecurity" returned Navy hardware notices (HOSE,NONMETALLIC, a WASHER) whose boilerplate DFARS/NIST clause text happened to contain the word, ahead of the opportunities actually about cybersecurity; a title-first/description-fallback split then hit the same problem one tier down — "cloud computing" fell to the description tier and surfaced a water-tank repair and an MRI renovation, because SAM.gov's posting templates insert standard cloud-computing-services clause language into unrelated notices regardless of scope, and phraseto_tsquery still matches that literal boilerplate phrase. Ranking fixes it at the source: a title hit contributes ~2.5x what a single description mention does, so it floats to the top of one result set instead of needing a hard tier cutoff to get right. Still strictly broader than the live API's title= parameter (fixed from a nonexistent keyword= param in fleet #311) — that only ever matches title at all. Every sam_search_opportunities response carries a mirror object reporting the snapshot's freshness (snapshot_date, rows_in_mirror) regardless of which path answered. The live API is used only when: no mirror is configured/loaded, or an explicit posted_from reaches past the mirror's snapshot_date (the default 30-day window never triggers this — only an argument you actually passed does). Single-opportunity lookup and set-aside search are unaffected — endpoint families the opportunities CSV doesn't cover, always live. Entity search and exclusions have since gained mirrors of their own (migration 135) and answer keyless by default.
sam_search_opportunities({keyword: "cybersecurity"}) → active RFPs.sam_set_aside_opportunities({set_aside: "SBIR"}) filtered by description.sam_entity_search({business_name: "X"}) → CAGE/UEI plus NAICS coverage.sam_search_exclusions (keyless). It answers "barred TODAY", not "ever barred": SAM.gov's daily Exclusions extract publishes only exclusions currently in force, so a debarment that has since been terminated is absent from the source entirely. include_terminated is accepted but cannot surface those — measured 2026-09-13, 400 sampled rows across four names with the filter disabled returned zero past termination dates. Treat an empty result accordingly.sam_entity_search returns both for cross-referencing.source field (sam.gov-mirror vs sam.gov-live) if results look thinner than expected.SBA (Small Business), 8A (8(a) program), WOSB (Women-Owned), SDVOSBC (Service-Disabled Veteran-Owned), HZC (HUBZone), SBIR (SBIR/STTR). Wrong code = empty result, not error."IT services" degrades badly — Postgres's english FTS config treats "IT" as a stopword and drops it, so the query silently becomes just "services" (~12k matches, mostly unrelated). "artificial intelligence", "cybersecurity", "cloud computing" and other multi-syllable/distinctive terms rank well; a bare 2-letter acronym doesn't. Prefer the spelled-out phrase ("information technology services", "help desk support") when the short form is a common English word.Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

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

}
}
tools/list at https://gateway.pipeworx.io/samgov/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.
curl -X POST https://gateway.pipeworx.io/v1/tools/sam_search_opportunities \
-H 'Content-Type: application/json' \
-d '{"keyword":"software development","naics":"541512","posted_from":"01/01/2024","posted_to":"12/31/2024","limit":20}'
No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/sam_search_opportunities. 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": {
"samgov": {
"command": "npx",
"args": ["-y", "@pipeworx/mcp-samgov"]
}
}
}
Or run it directly to confirm it starts:
npx -y @pipeworx/mcp-samgov
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 Samgov data" })
The gateway picks the right tool and fills the arguments automatically.
