Included Packs
Live RFPs/RFQs/IFBs vendors can currently respond to, from 19 city & county procurement portals updated daily — PennBid (PA statewide), Utah U3P (statewide), Harris County TX, Charlotte NC, Dallas, Fort Worth, Cook County IL and more. We never delete a closed bid, so sold-history accumulates over time.
Who won last time, for how much, and what the agency actually paid — normalized across 8 state/county/city contract registries (TX, WA, VA statewide, King County WA, NYC, Chicago, Cook County IL, Austin) plus 7 state checkbook-spending feeds (NJ, VT, OR, MD, MO, CT, Dallas).
Active federal contract opportunities by keyword, NAICS code and small-business set-aside (SDVOSB, HUBZone, 8(a), WOSB), plus registered-contractor and exclusion-list lookups. Uses Pipeworx's shared SAM.gov key.
Setup
Choose one of these options:
Open claude.ai/customize/connectors, click Add custom connector, name it Pipeworx US Tenders and paste this URL. Leave the OAuth client ID and secret blank — the connector registers itself.
https://gateway.pipeworx.io/mcp?vertical=us-tendersThen click Connect and sign in with GitHub. That step is free and takes you from 50 calls a day to 200 — same connection either way, and you can skip it and sign in later. In a new chat, open the tools menu and enable the connector.
Custom connectors need a paid Claude plan — that is an Anthropic gate, not a Pipeworx one.

Then tell me what open construction bids Cook County, IL and Harris County, TX have right now, and who won their last few awarded contracts over $1M.Open bids and awarded-contract/spending data are keyless, official government sources. Federal SAM.gov opportunities run on Pipeworx's shared key — no SAM.gov account required either.

What data sources are included in US Tender Radar?
Open bid solicitations from 19 city and county procurement portals (PennBid statewide PA, Utah U3P statewide, Harris County TX, Cook County IL, Charlotte NC and more), awarded state/local contracts from 8 jurisdictions (Texas, Washington, Virginia statewide, King County WA, NYC, Chicago, Cook County IL, Austin), state checkbook spending from 7 states (New Jersey, Vermont, Oregon, Maryland, Missouri, Connecticut, Dallas), and federal opportunities from SAM.gov. All keyless except SAM.gov, which runs on Pipeworx’s shared key.
Is this the same as the international Tender Radar?
No. They are two bundles because they answer two different questions, and because US coverage grew past 30 jurisdictions on its own. This one is for bidding on US government work. Tender Radar covers the EU, the UK, Ukraine and 13 more national portals.
Does this cover awarded contracts or just open bids?
Both, plus what an agency actually paid. open_bids_search finds solicitations vendors can respond to right now; gov_contracts_search returns who won past awards and for how much; gov_spending_search returns the checkbook data — actual vendor payments, which can differ from the awarded contract value. For someone deciding whether and how to bid, who won last time and what the agency really pays is part of the decision.
Do I need a SAM.gov account for the federal tools?
No. sam_search_opportunities, sam_get_opportunity, sam_set_aside_opportunities, sam_entity_search and sam_search_exclusions all run on Pipeworx’s shared SAM.gov key — no registration required to search. You still need your own SAM.gov registration (a UEI) to actually submit a federal bid.
How current is the bid and contract data?
Open bids refresh daily from each portal. Awarded-contract and spending datasets follow each jurisdiction’s own publishing cadence (most weekly to monthly) — gov_contracts_jurisdictions reports the live record count per source so an agent can see how current a given jurisdiction is. Closed bids are retained rather than deleted, so open_bids_search with status:"closed" or "all" can also answer what a jurisdiction has bid out historically.
