# Cursor
## Manual
Add the server to `~/.cursor/mcp.json` (all projects), or to `.cursor/mcp.json` in one project:
```json
{
"mcpServers": {
"justclaw-it": {
"url": "https://justclaw.it.com/mcp",
"headers": { "Authorization": "Bearer <YOUR_API_KEY>" }
}
}
}
```
Replace `<YOUR_API_KEY>` with your key. If the file already has servers, add `justclaw-it` inside the existing `mcpServers` object. Keep a project-level file that holds your key out of version control.
## Check it
Open Cursor's MCP settings: `justclaw-it` should show as enabled with its tools listed. If it shows an error, check the URL ends in `/mcp` and the header is exactly `Bearer ` followed by the key.
## Try it
In Agent mode:
> Search JustClaw-It for a TypeScript retry with exponential backoff helper, min composite 6, and add the best one to src/lib.
