Deletes or cancels 3Removes, cancels or revokes something.Claude Code: deny

clockify_delete_time_entryWRITE (destructive): permanently delete one time entry.No findings
Why it is in this group
- The name "clockify_delete_time_entry" says "delete": a word for removing or ending something.
- The description says "permanently delete".
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
WRITE (destructive): permanently delete one time entry. It cannot be undone. DELETE /v1/workspaces/{workspaceId}/time-entries/{id}.
Annotations the server declares
- title: Delete a time entry
- readOnlyHint: false
- destructiveHint: true
- idempotentHint: true
- openWorldHint: true
clockify_stop_timerWRITE: stop the running timer of a user (default: you) at end (default now).No findings
Why it is in this group
- The name "clockify_stop_timer" says "stop": a word for a change.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
WRITE: stop the running timer of a user (default: you) at end (default now). Clockify answers 404 if no timer is running. PATCH /v1/workspaces/{workspaceId}/user/{userId}/time-entries.
Annotations the server declares

Why it is in this group
- The name "clockify_update_time_entry" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
WRITE: change a time entry's start, end, description, project, task, tags or billable. Only the fields you pass change: the entry is read first and every other field (custom fields included) is sent back as it was. The entry is rewritten (PUT) from a fresh read, so an edit made to the same entry in between (e.g. in the Clockify app) can be lost. A new project without task_id clears the task. GET then PUT /v1/workspaces/{workspaceId}/time-entries/{id}.
Annotations the server declares
- title: Update a time entry
- readOnlyHint: false
- destructiveHint: true
- idempotentHint: true
- openWorldHint: true

10 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.
