## 🔀 Sibling versions
Sink and [Slite](https://github.com/miantiao-me/Slite) are sibling versions of the same link-management and analytics project. Sink runs on Cloudflare's serverless platform, while Slite runs as a local Node.js 24+/Docker process. They keep features, API contracts, and file organization compatible with each other wherever practical. Neither version is a legacy branch, and Slite is not a fork replacement for Sink.

## 🧰 MCP
Sink serves a built-in MCP endpoint at `POST /api/mcp`, using the official `@modelcontextprotocol/server` SDK v2, serving modern clients over the per-request transport and 2025-era clients over a stateless fallback with JSON responses.
> Replace the domain below with your own instance, and use the `NUXT_SITE_TOKEN` from your instance's environment variables as the bearer token.
```sh
claude mcp add --transport http sink https://sink.cool/api/mcp --header "Authorization: Bearer SinkCool"
```
Any client that supports an HTTP transport with custom headers can connect the same way:
```json
{
"mcpServers": {
"sink": {
"type": "http",
"url": "https://sink.cool/api/mcp",
"headers": {
"Authorization": "Bearer SinkCool"
}
}
}
}
```
It exposes tools for managing links (list, search, read, count, tag, create, update, upsert, delete) and for reading analytics (counters, views over time, and top values per dimension). See the [integrations documentation](https://docs.sink.cool/integrations/) for the full list.
