ChangeDetection.io MCP Server
Gives Claude direct access to your ChangeDetection.io instance for monitoring website changes. You get the full API: create and manage watches, pull change history, diff any two snapshots, search by URL or title, and organize with tags. Ships with a configurable safety fuse that limits cascading mutations per watch after viewing a diff, so one noisy page won't trigger unlimited rechecks. Useful when you want an agent to set up monitoring on product pages, check what changed on a tracked site, or manage your watch list without touching the web UI. Requires a running ChangeDetection.io instance and API key.
