Connects to SAM.gov, DLA DIBBS, CalProcure and other government procurement platforms. Lets you search open solicitations by trade, location, agency and deadline, read bid documents, and track opportunities you're pursuing.

Example request: "Find all open electrical contracting bids in California closing within 30 days."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use NextBid to help me. It is a free service with an MCP server at https://api.nextbid.us/mcp. It needs an API key from NextBid; ask me to enter it through your secure credential prompt. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- search_opportunities: Search open government solicitations (SAM.gov, DLA DIBBS, CalProcure, OpenGov, PlanetBids, PublicPurchase, Bonfire, and agency notices syndicated by InstantMarkets) in NextBid's normalized corpus. Returns one deduplicated record per opportunity with agency, deadline, codes, docum
- get_opportunity: Full record for one opportunity by NextBid id (NB########): description, AI summary, buyer contacts (current and historical), amendments, filed documents. One request; counts as a delivered solicitation the first time this account receives it.
- list_documents: The document set for one opportunity: source_documents (listed by the source engine: name, size, sha256, source url, whether NextBid stores the original) and nextbid_documents (the current Document 0 and normalized text, readable with read_file). Pipeline artifacts are counted, n
- get_document_download: A time-limited download link for one stored original document of an opportunity (sha256 from list_documents, where stored is true). One request; the file is served by NextBid's object store, not through the API.
- get_evidence: The evidence for one opportunity: every indexed document (identity, version, hashes, whether the original is downloadable, whether the AnyDoc extracted text is verified) and the Graphify claims - each a GENERATED label with the SOURCE passage it cites (document, UTF-16 offsets, e
- get_document_text: The AnyDoc extracted text of one document (sha256 = the text sha256 or the original sha256 from get_evidence), verified against its indexed hash. Offsets in get_evidence index into this text. One request.
- list_files: The current stored documents for one opportunity: Document 0 markdown/json and normalized attachment markdown (class document0 / normalized_text). include="all" adds pipeline artifacts (case files, graphs, packets) and superseded Document 0 generations. Use read_file to fetch one
- read_file: Read one stored text artifact of an opportunity (path from list_files). Returns the text, truncated to max_chars (default 60,000).
- corpus_stats: The corpus numbers with their definitions: total_solicitations (distinct, duplicates excluded), open (listed open by the source with the deadline ahead or unstated, or deadline ahead with no status; passed deadlines and unknown status are separate: listed_open_past_deadline, stat
- list_set_asides: Set-aside and small-business programs NextBid recognizes (federal SBA programs, California SB/DVBE, open competition): id, name, level, what it means, official reference, aliases and today's counts split into open_designated (source-marked) and open_mentioned (title language only
- my_account: The account's meter: plan, allowance used and remaining, period reset or trial expiry, keys, what counts as a call, how to upgrade, and the business profile. Free.
- mark_pursuit: Record that the customer is watching, pursuing, has submitted, won, lost or dropped an opportunity. Call it only when the customer says so; reading a bid is never a pursuit. Free.
- list_tradelines: The trade catalog: each trade id with its name, description, specialties and search aliases, plus today's open count. Use an id or any alias in search_opportunities. Specialties describe supported categories, not open bids.
- my_usage: The account's meters: requests used and remaining, unique solicitations delivered and remaining, plan period or trial expiry. Free.
