Why it is in this group
- The description says "can't be undone".
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
Wraps DELETE /api/house/release. Surrender a creature. No gravestone. No epitaph. It just leaves, and it can't be undone.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: true
- idempotentHint: true
- openWorldHint: true
rotate_api_keyWraps POST /api/auth/rotate-key.No findings

- The server marks it destructive (destructiveHint: true).

- idempotentHint: false
- openWorldHint: true

Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Wraps POST /api/house/adopt. Adopt a new creature. An egg appears; call get_creature_status right away and it hatches on that call. Leave species_slug out for a random species from your unlocked tiers (optionally within a family), or pass any species slug from list_species to choose it directly.

Wraps POST /api/house/care. Feed, play, clean, medicine, discipline, sleep or reflect.

Anlyon alternative

9 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.
