🔀 Sibling versions

Sink and 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.

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:

{
  "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 for the full list.
