replicate_agent · CustomGPT MCP Server MCP: Risk & Policy

WHAT IT DOES

What replicate_agent does on CustomGPT MCP Server

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

WHY IT NEEDS A POLICY

Why replicate_agent needs a policy

This tool creates a new copy of an existing agent, which is a reversible write operation (creation of a new resource). It does not delete or modify existing data, execute code, or involve financial transactions. The blast radius is medium since it duplicates an agent with all its associated settings and files, potentially consuming resources or exposing sensitive configurations in the clone.

From the tool's definition Replicate/clone an agent by copying all its info, settings, sources and files.
