Acquisition.gov MCP

Read-only, deterministic MCP access to the official Acquisition.gov FAR Overhaul (RFO) model-part pages, the posted agency-deviation index, official deviation PDFs, and a small allowlist of RFO guidance resources.

This server reports source content and metadata. It does not decide which rule governs a procurement. In particular, model deviation text is not treated as operative for an agency without that agency's posted deviation.

Install

uvx acquisition-gov-mcp==1.0.4

The server uses stdio, requires no credentials, and defaults to a three-second cross-process interval between Acquisition.gov requests. FEDERAL_API_MIN_INTERVAL_SECONDS may increase or decrease that interval for controlled testing; production clients should retain three seconds.

Tools

Tool	Purpose
`list_rfo_parts(part?, agency?, updated_since?)`	List RFO model parts with official source dates and matching posted-deviation counts.
`get_rfo_part(part, section?, cursor?, max_characters?)`	Retrieve parsed, paginated model text for one FAR part.
`list_rfo_agency_deviations(agency?, part?, limit?)`	Discover posted deviation documents. At least one filter is required.
`get_rfo_agency_deviation(source_id, page_start?, page_end?)`	Resolve only an indexed source ID and return page-numbered PDF text and document-found applicability language.
`get_rfo_guidance(resource, heading?, cursor?)`	Retrieve the FAQ, policy-and-guidance page, or FAR Council deviation-guidance PDF.

Every retrieved source includes a canonical URL, UTC retrieval time, SHA-256 content hash, extraction status, and warnings. Agency PDF dates and applicability are returned only when labeled language is found inside the document; filenames are never used to infer them.

Safety boundary

Only https://acquisition.gov and https://www.acquisition.gov are allowed.
Redirect targets are revalidated; credentials, explicit ports, arbitrary hosts, and private IP targets are rejected.
Responses are limited by content type, bytes, redirects, pages, and output length.
HTTP 429 is not burst-retried. Retry-After is retained in the shared pacing state.
If the Python TLS transport stalls against Acquisition.gov's CDN, the server may use an installed system curl for the same prevalidated URL; redirects remain disabled and revalidated by the server.
Duplicate and conflicting index entries are returned with warnings instead of silently resolved.
Scanned, encrypted, and malformed PDFs return explicit extraction status and metadata where possible.

See testing.md for the release evidence and live-gate instructions.
