nwo_update_agent · NWO Robotics MCP: Risk & Policy

WHAT IT DOES

What nwo_update_agent does on NWO Robotics

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

WHY IT NEEDS A POLICY

Why nwo_update_agent needs a policy

This is a Write operation (modifies agent configuration reversibly). Severity is high because the server controls real robots and IoT devices, and agents have financial capabilities (ETH payments). An AI agent with access to this tool could maliciously reconfigure another agent to execute unauthorized robot actions or financial transactions.

From the tool's definition Tool name 'nwo_update_agent' and description 'Update agent capabilities or configuration' indicate modification of agent state.
