# Is there an MCP server for SAM.gov I can use with Claude or ChatGPT? Yes, several. The open-source sam-gov-mcp package wraps the official SAM.gov APIs (hosted edition keyless with 6 tools, local edition on your own SAM.gov key). GovCon API ships an MCP server on its paid plans. samgovapi.io hosts one at samgovapi.io/api/mcp with keyless search and fetch, plus 20 data tools with a free key. The choice comes down to where the data comes from.Checked on 2026-11-15.Source: [Model Context Protocol](https://modelcontextprotocol.io/) | Endpoint | https://samgovapi.io/api/mcp | | --- | --- | | Transport | Streamable HTTP, stateless | | Keyless tools | search, fetch, signup, feedback | | Auth for data tools | Authorization: Bearer | ## The answer in detail The choice comes down to where the data comes from. Servers that call SAM.gov live inherit its limits: a local sam-gov-mcp on a no-role key stops after 10 calls a day, which an agent can spend on one question. Servers over a loaded copy answer more calls but are as fresh as their last load.This server speaks Streamable HTTP (stateless JSON-RPC over POST). Keyless tools: search, fetch, start_signup, finish_signup and give_feedback. With a key: registration_status, get_entity, search_entities, search_opportunities, get_opportunity, exclusion_check, search_awards, recompetes, naics_lookup, size_standard_check, labor_rates, expiring_registrations and alert tools; teaming_partners on Pro.Claude Code, Cursor, VS Code, Windsurf and Claude Desktop take the URL and a Bearer header. ChatGPT's custom MCP connectors cannot send a key header, so they get the keyless tools. ## How the options compare | Option | Price | Access and limits | Coverage and history | Best for | Checked | | --- | --- | --- | --- | --- | --- | | [sam-gov-mcp (open source, PyPI)](https://pypi.org/project/sam-gov-mcp/) | Free | Hosted edition: no key, 6 tools; local edition: 20 tools on your own SAM.gov key, so SAM.gov's daily limits apply | Wraps the official SAM.gov REST APIs live (version 1.0.18, released 27 Oct 2026) | Agents that need a few live SAM.gov calls a day | 2026-11-15 | | [GovCon API (govconapi.com)](https://govconapi.com/pricing) | Developer $19/mo, Pro $39/mo; 14-day trial | 1,000 requests an hour (50 a minute burst); trial 50 a day | 12,265,150 contracts and 758,552 opportunities from FY2025; 904,090 entities, monthly | Developers who want the lowest entry price and FY2025+ history | 2026-11-15 | | [SAM.gov APIs (official)](https://open.gsa.gov/api/entity-api/) | Free | 10 requests a day with no SAM.gov role, 1,000 with a role or a non-federal system account; keys expire every 90 days | The live, authoritative record: entities, opportunities, exclusions, contract awards, hierarchy, subawards | Anyone who needs the official record itself, at low volume | 2026-11-12 | | [samgovapi.io](https://samgovapi.io/pricing) | Free (100 credits a month, no card); Developer $49/mo, Pro $149/mo, Scale $499/mo | 20 to 180 requests a minute by plan, no daily cap; REST, MCP and keyless MCP search | 881,370 entities (1 Nov 2026 extract), 74,420 notices, 169,191 exclusions, 114,954 awards since 1 Oct 2026 | Developers and AI agents who want entities, bids and exclusions joined in one API | 2026-11-15 | ## Where samgovapi.io is the weaker choice - A live-API server sees changes the same day; this one is as fresh as the nightly and monthly loads. - Award history is short: 114,954 prime awards with action dates from 1 Oct 2026 to 10 Nov 2026 (fiscal year 2027 so far).
