THE RISK

Low Risk

Why search_conversations needs a policy

This tool retrieves and queries conversation data without creating, modifying, deleting, or executing anything. It is a passive information retrieval operation with no side effects, fitting the Read category.

From the tool's definition Tool performs 'full-text search across all Claude Code conversations' with no indication of modification, deletion, or execution capabilities. The verb 'search' and 'find' indicate retrieval operations only.

POLICY

How to control search_conversations

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "search_conversations": {}
  }
}

search_conversations is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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