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