Why proxy_search_traffic needs a policy

This tool reads and searches existing captured network traffic data without modifying, deleting, or executing any operations. It is purely informational and has no side effects beyond returning search results. The low severity reflects that search capabilities over traffic logs pose minimal risk even if misused by an AI agent.

From the tool's definition Tool performs 'full-text search across URLs, headers, and body previews of captured traffic' - a retrieval/query operation with no modification or execution capability.

How to control proxy_search_traffic

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "proxy_search_traffic": {}
  }
}

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

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