pt_move_device · MCP Packet Tracer MCP: Risk & Policy

WHAT IT DOES

What pt_move_device does on MCP Packet Tracer

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

WHY IT NEEDS A POLICY

Why pt_move_device needs a policy

Moving a device changes its position state in the Packet Tracer topology visualization, which is a reversible modification. It does not execute commands, delete data, access sensitive information, or affect financial systems. The change is non-destructive and can be easily undone by moving the device to another position. This qualifies as a Write operation with low severity due to its limited scope and reversibility.

From the tool's definition Tool name 'pt_move_device' and description 'Mueve un dispositivo a nuevas coordenadas en el canvas de Packet Tracer' (Moves a device to new coordinates on the Packet Tracer canvas). This modifies the visual layout/position of a device in the simulation canvas.

Verdict

pt_move_device Rate-limited

pt_move_device 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.

FAQ

Questions about pt_move_device

What does the pt_move_device tool do? +

Mueve un dispositivo a nuevas coordenadas en el canvas de Packet Tracer. It is categorised as a Write tool in the MCP Packet Tracer MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on pt_move_device? +

Register the MCP Packet Tracer MCP server in PolicyLayer and add a rule for pt_move_device: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MCP Packet Tracer. Nothing to install.

What risk level is pt_move_device? +

pt_move_device is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit pt_move_device? +

Yes. Add a rate_limit block to the pt_move_device rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block pt_move_device completely? +

Set action: deny in the PolicyLayer policy for pt_move_device. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides pt_move_device? +

pt_move_device is provided by the MCP Packet Tracer MCP server (mainorcruz/mcp_packet_tracer). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
