Most SAM.gov MCP servers wrap one dataset behind six to ten tools. This is 53 tools across five federal sources, already joined on the identifiers they share, including full text extracted from inside solicitation attachments.
US federal procurement data for agents: 668K SAM.gov opportunities, 10.6M FPDS prime contract transactions, 880K SAM-registered entities, 226K FFATA subawards, 164K exclusions, 14K decided GAO protests, and ~262K GSA CALC labor rates. Cross-linked on UEI, CAGE, PIID and NAICS, so one question does not become five integrations.
Counts as of 2026-08-31, rounded. The corpus grows daily, so this file is a snapshot: current per-source totals and freshness dates are always live at /api/v1/status, no key required.

Most federal-contracting MCP servers are thin proxies over the official SAM.gov API. Four concrete differences.
- It searches inside the documents, not just the notice. We extract and index the full text of every document attached to a notice. A corpus study on 2026-07-16 measured 506,382 documents across 209,095 opportunities, 31.4 billion characters, including 57,527 files recovered from archives nested up to five levels deep that never appear in SAM's own attachment list, and 41,764 scanned documents recovered with OCR. Those five figures are one dated measurement and belong together; the index has grown since, and the running total is on
/api/v1/status. A requirement like CMMC, a clearance level, or an option year is usually in the SOW, not the notice. Most tools structurally cannot see it. - Five sources, already joined. SAM.gov opportunities and entities, FPDS contract transactions, USAspending/FFATA subawards, SAM exclusions, SBA DSBS certifications and GSA CALC rates, resolved onto shared identifiers. A wrapper hands your agent one dataset and leaves the joins to it.
- No SAM.gov entity registration and no company UEI required. GSA documents 10 requests/day for a non-federal user without a SAM role, and 1,000/day with one. Access here is an email and a key.
- 53 tools, organised by lifecycle stage. Market research, opportunity discovery, capture and teaming, bid and negotiate, award and compliance. You should not have to know our URL structure to know which tool answers your question.
pipx install govconapi-mcppipx puts the binary somewhere Claude Desktop's sandbox can spawn it. On macOS, brew install pipx first. With uv, use uvx --from govconapi-mcp govconapi-mcp. Python 3.10+.

| Opportunity discovery | 3 | what is live now that matches my capability |
| Capture and teaming | 12 | who is winning, who to team with, who to call |
| Bid, price and negotiate | 9 | what it should cost, labor rates, is my team clean |
| Award and compliance | 13 | who won, on what terms, was it protested |

13 tools require Pro and return HTTP 402 on Developer. 4 more work on Developer with specific fields or filters gated. The other 36 have no plan distinction. Each is marked in TOOLS.md.
- Not a replacement for SAM.gov as the system of record. We normalize public federal data and preserve source provenance. For the authoritative record, or for a submission, go to SAM.gov.
- Not real-time. Opportunities refresh daily. If your use case turns on minute-level freshness, this is the wrong tool and we would rather you knew now.
- Not state or local. US federal procurement only.
- Not a proposal writer, CRM, or BD platform. It is a data layer. If you want an end-to-end capture suite, buy one of those instead and point it here.
- FPDS coverage starts 2024-10-01 (FY2025 onward). Deep multi-year historical market research is a real limitation, not an oversight.
- Source defects pass through. SAM and FPDS contain impossible dates, $0 amounts and null UEIs. We surface them as they are and document the gotchas rather than silently cleaning them, because the corruption belongs to the system of record.

What this server does with your data, in short:
- Your API key is read from
GOVCONAPI_KEYin your own client's config and sent tohttps://govconapi.comin theAuthorizationheader. This server process does not write it to disk or transmit it anywhere else. - Your tool calls become ordinary GovCon API requests. As with any request to the API, we log the timestamp, endpoint, query parameters, response status, response time and which key made the call, for billing, rate-limit enforcement and abuse detection. Usage logs are retained for 90 days.
- No conversation content leaves your machine. Only the tool parameters your client fills in are sent, never the surrounding chat, and we log the status a request returned, not the contents of the response.
- We do not sell your data.
- The data returned is public US federal procurement data from SAM.gov, FPDS, USAspending, SBA DSBS and GSA CALC.
