kv2-delete
AI agents call kv2-delete to permanently remove resources in Vault MCP Server (mschuchard) — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool deletes secrets from Vault's KV v2 secret engine, which is an irreversible destructive action. Even though the description is empty, the tool name combined with the server's stated purpose (managing secret engines like KV v2) makes the destructive nature clear. Deletion of secrets cannot be undone and represents a critical blast radius if invoked incorrectly by an AI agent on the wrong secret paths.
From the tool's definition Tool name 'kv2-delete' explicitly indicates deletion of KV v2 secrets. KV v2 is HashiCorp Vault's key-value secret engine. The 'delete' operation is irreversible data destruction.
