clear_conversation_history

THE RISK

Critical Risk

This tool irreversibly deletes data (conversation history). While the blast radius is limited compared to system-wide deletions, the data loss is permanent and unrecoverable. This meets the definition of Destructive rather than Write (which is reversible).

From the tool's definition Tool name explicitly uses 'clear' which indicates irreversible deletion. Description states 'Clear conversation history' without qualification or undo capability. The action permanently removes accumulated conversation data that cannot be recovered.

HOW TO CONTROL CLEAR_CONVERSATION_HISTORY

PolicyLayer is an MCP gateway — it sits between your AI agents and Second Opinion MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for clear_conversation_history:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "clear_conversation_history"
  ]
}

clear_conversation_history disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Second Opinion MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
