RECOMMENDED RULE

The rule that runs util_merge_shallow safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Delx MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For util_merge_shallow, this is the rule to start with:

util_merge_shallow Rate-limited

util_merge_shallow stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
