  "markdown": "# whetstone-mcp\n\nAn [MCP](https://modelcontextprotocol.io) server for **U.S. public-records data** — so AI\nagents and MCP clients (Claude Desktop, Cursor, etc.) can look up business records,\nscreen names against government watchlists, and pull federal awards directly.\n\nPowered by the [Whetstone](https://whetstonetools.com/company-check/) actors on Apify. All\ndata is official U.S. government public-record data.\n\n## Tools\n\n| Tool | What it does |\n|---|---|\n| `business_search` | Official Secretary of State business registration (KYB) across 25 states |\n| `new_business_filings` | Newly registered businesses from 10 states, windowed by date |\n| `watchlist_screen` | Screen a name against 12 federal watchlists (OFAC, BIS, State Dept) |\n| `federal_awards` | A company's federal contracts, grants, and loans (USAspending.gov) |\n\n## Setup\n\nYou need a free **Apify API token** (apify.com → Settings → API & Integrations). Runs bill\nto your Apify account under pay-per-result pricing (~$2 per 1,000 result rows; the free tier\ncovers light use).\n\n### Claude Desktop\n\nAdd to `claude_desktop_config.json`:\n\n```json\n{\n  \"mcpServers\": {\n    \"whetstone\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"whetstone-mcp\"],\n      \"env\": { \"APIFY_TOKEN\": \"apify_api_your_token_here\" }\n    }\n  }\n}\n```\n\nRestart Claude Desktop. The four tools then appear and the agent can call them.\n\n### Any MCP client\n\nRun the server over stdio:\n\n```bash\nAPIFY_TOKEN=apify_api_... npx -y whetstone-mcp\n```\n\n## Notes & limits\n\n- **Heavy queries can be slow.** Business search across all 25 states (or filings across all\n  10) runs synchronously and may approach the 300-second limit. Pass a `states` subset for\n  faster, cheaper runs.\n- **Name-based matching.** Watchlist and federal-award results are matched by name and are\n  **not identity confirmation** — verify a hit against the official source before acting.\n  Nothing here is legal, compliance, or financial advice.\n- A free, interactive version of the combined lookup is at\n  [whetstonetools.com/company-check](https://whetstonetools.com/company-check/), and there's\n  also an [n8n community node](https://www.npmjs.com/package/n8n-nodes-whetstone).\n\n## License\n\n[MIT](LICENSE) © Whetstone Tools · support@whetstonetools.com\n",
