pt_list_modules
AI agents call pt_list_modules to retrieve information from MCP Packet Tracer without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'list' verb denotes a query/retrieval action typical of Read operations. Even in the context of Packet Tracer network topology control, listing modules has no destructive, financial, or code-execution implications. Confidence is slightly reduced due to the absent description, but the tool name itself is strong evidence for the Read category.
From the tool's definition Tool name 'pt_list_modules' follows the 'list' pattern, which per classification rules indicates a retrieval operation with no side effects.
Attacks that exploit this kind of access
pt_list_modules. It is categorised as a Read tool in the MCP Packet Tracer MCP Server, which means it retrieves data without modifying state.
Register the MCP Packet Tracer MCP server in PolicyLayer and add a rule for pt_list_modules: 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.
pt_list_modules is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the pt_list_modules 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.
Set action: deny in the PolicyLayer policy for pt_list_modules. 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.
pt_list_modules 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.
