WHAT IT DOES

What batch_copy does on Mcp Hands

AI agents use batch_copy to create or update resources in Mcp Hands, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Hands environment.

RISK

Why batch_copy is rated Medium

An AI agent can call batch_copy faster than any human can review: one bad instruction and it creates or modifies resources in Mcp Hands by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs batch_copy safely

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

batch_copy Rate-limited

batch_copy 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.
