## Install as an MCP server
Point any MCP client (Claude Desktop, Cursor, Windsurf, etc.) at the hosted MCP server at `https://mcp.kool.ink` — no API key required for anonymous shortening.
```json
{
"mcpServers": {
"koolink": {
"url": "https://mcp.kool.ink"
}
}
}
```
## Tools
This server exposes the following MCP tools:
| Tool | Description | Input |
|---|---|---|
| `shorten_url` | Shorten a long URL and return a compact kool.ink short link. | `{ "url": "<long-url>" }` |
## Why KooLink
- **Free forever** — no account, no credit card, no limits
- **Clean, memorable URLs** — `kool.ink/xyz`, not `bit.ly/4xdK9qZ`
- **AI-agent ready** — same service over MCP at `https://mcp.kool.ink`, or the REST API
- **Analytics** — every link is click-tracked with bot traffic filtered out
- **Creator Earning Programme** — as traffic grows, you earn
## API
The CLI calls the public anonymous endpoint:
```bash
curl -X POST https://kool.ink/api/links \
-H "Content-Type: application/json" \
-d '{"url":"https://example.com"}'
```
For AI agents, use the MCP server at `https://mcp.kool.ink` (no API key needed for anonymous shortening).
