Overview

SAM.gov MCP

A Model Context Protocol server that wraps the SAM.gov REST APIs as deterministic tool calls. Built for federal contracting officers, GS-1102 contract specialists, and small business government contractors who need plain-English access to SAM.gov entity, exclusion, opportunity, and contract award data.

19 tools. Live-tested across multiple audit rounds against production SAM.gov endpoints. MIT licensed.

What it does

Entity Management: UEI/CAGE/DUNS lookups, registration status, business types, NAICS/PSC codes, reps and certs, points of contact, addresses, eligibility validation.

Exclusions: single-entity check by UEI/CAGE, exclusion list search by name/agency/type. Returns exclusion type, CT codes, termination dates.

Contract Opportunities: search active solicitations by NAICS, set-aside (Total Small Business, 8(a), SDVOSB, WOSB, EDWOSB, HubZone, unrestricted), agency, posting date. Pull sources sought, presolicitations, combined synopsis/solicitations, award notices.

Contract Awards (FPDS replacement): search by PIID, vendor UEI, agency, NAICS, PSC, fiscal year. Modification history, vendor profiles, ceiling/obligated, contract type, competition data.

Federal Hierarchy: department, sub-agency, office lookups. CGAC, sub-tier, office code normalization. Mapping between FPDS contracting office codes and SAM.gov hierarchy.

FFATA Subawards: search and detail.
