Monitors web pages and text or JSON URLs by storing snapshots and reporting changes between checks.

機能

ツール

4 ツール
check_watch
Re-fetch a watched page and report whether it changed since the last check, with a short list of added/removed content lines. Updates the baseline to the new content. Call this every time you want the latest status (e.g. each run/heartbeat).
入力スキーマ 
{'type': 'object', 'required': ['watch_id', 'token'], 'properties': {'token': {'type': 'string', 'description': 'The token returned by create_watch.'}, 'watch_id': {'type': 'string'}}}
create_watch
Start monitoring a web page (or JSON/text URL) for changes. Captures a baseline snapshot now. Returns a watch_id and a token — save the token; it's how you check and manage your watches later. Pass an existing token to add more watches under the same account.
入力スキーマ 
{'type': 'object', 'required': ['url'], 'properties': {'url': {'type': 'string', 'description': 'Absolute http(s) URL to monitor, e.g. https://example.com/pricing'}, 'label': {'type': 'string', 'description': 'Optional human label for this watch.'}, 'token': {'type': 'string', 'description': 'Optional. Your existing Kestrel token to group this watch with others. Omit to get a new token.'}}}
delete_watch
Stop monitoring a page and delete the watch.
入力スキーマ 
{'type': 'object', 'required': ['watch_id', 'token'], 'properties': {'token': {'type': 'string'}, 'watch_id': {'type': 'string'}}}
list_watches
List all watches under your token, with per-watch check/change counts.
入力スキーマ 
{'type': 'object', 'required': ['token'], 'properties': {'token': {'type': 'string'}}}
