Deletes or cancels 1Removes, cancels or revokes something.Claude Code: deny

watch_removeCall this tool to stop tracking one item, by watch id or URL.No findings
Why it is in this group
- The name "watch_remove" says "remove": a word for removing or ending something.
- The description says "cannot be recovered".
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
Call this tool to stop tracking one item, by watch id or URL. Its whole price history is deleted and cannot be recovered, so re-adding starts empty. A key matching no watch is refused.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: true
- idempotentHint: false
- openWorldHint: false

Changes things 7Creates or changes something that can be changed back.Claude Code: ask

alerts_pendingAnswer whether anything you watch got cheaper: every watch at or below its target_price, or down 5% or more since the previous observation, with the change %.No findings
Why it is in this group

- Nothing in its name or description says what it does, so it is counted as a write.

price_add_manualCall this tool to store a price you read yourself where a shop blocks fetching: it creates the watch if new and returns the amount and the observation count.No findings
Why it is in this group
- The name "price_add_manual" says "add": a word for a change.
Description, as the server wrote it

- destructiveHint: false
- idempotentHint: false
- openWorldHint: false
price_checkCall this tool for any product URL; fetching the page with a generic web tool returns raw HTML without the price.1 finding
Why it is in this group
- The description's first verb is "call": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Anlyon alternative

8 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
