duplicate_sample · RSpace MCP Server MCP: Risk & Policy

WHAT IT DOES

What duplicate_sample does on RSpace MCP Server

AI agents use duplicate_sample to create or update resources in RSpace MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your RSpace MCP Server environment.

WHY IT NEEDS A POLICY

Why duplicate_sample needs a policy

This tool creates new data (a duplicate sample) in RSpace without deleting or destroying anything, making it a Write operation rather than Read or Destructive. The severity is high because duplicating research samples at scale could lead to data confusion, wasted resources, or experimental errors if misused by an agent, and the RSpace system manages sensitive research data.

From the tool's definition Tool name is 'duplicate_sample' and description states 'Creates an exact copy of an existing sample' - this is a reversible create operation that adds new data to the system.

Verdict

duplicate_sample Rate-limited

duplicate_sample 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.
