Tools

Scopes are chosen per key — a read-only key can report on links without being able to change anything. Every request is visible in per-key usage analytics.

Plans

The MCP server itself is free on every plan. Sinkto.Link's free tier: unlimited links, unlimited clicks, unlimited team members.

Why

Every URL shortener caps its free plan — Bitly at 5 links/month, TinyURL at 30, Short.io at 1,000 lifetime. Sinkto.Link doesn't. The MCP server exists so AI assistants can manage that link infrastructure the same way their human owners do.
