  "description": "OSF Data Marketplace: over 7.5 million US government and scientific records with provenance for AI agents. Remote MCP over streamable HTTP, no install, no API key and no account: add https://api.osf-master-server.com/mcp to any MCP client. 21 tools and 15 of them are free, including the catalog, 13 vertical searches and screen_entity_free, a real sanctions AND DEBARMENT screen (SAM.gov federal exclusions, HHS OIG healthcare exclusions, World Bank, Federal Reserve, OFAC, EU, UK, UN) 5 times a day with no signup and no key, so an agent can confirm the data exists and get a real answer before spending. The 6 paid tools cover a $0.001 sample any record micro tier plus screening across sanctions, cyber, legal, SEC, research, health, patents, aircraft registry, AI models, lobbying disclosures, nonprofit registries and live FINRA broker checks, settled per call via x402 USDC on Base. The sanctions screen returns NO_MATCH only when the complete candidate set on all 11 authority lists was examined, otherwise INCOMPLETE_SCREEN, so a negative is provable rather than assumed.",
