Detect one-sided capture symptoms: SYN without ACK, lost segments, ICMP-in-tunnel.
AI agents call pm_asymmetric_hints to retrieve information from PacketMaster without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs passive analysis of network packet captures to identify anomalies and diagnostic patterns. It reads and queries packet data to report findings about asymmetric network conditions, which is a classic Read operation. There are no side effects, no data modification, no command execution, and no destructive or financial implications.
From the tool's definition pm_asymmetric_hints is a detection/analysis tool that 'Detect[s] one-sided capture symptoms: SYN without ACK, lost segments, ICMP-in-tunnel.' The action verbs are analysis-focused (detect, analyze) applied to existing PCAP data with no capability to modify,…
Attacks that exploit this kind of access
Detect one-sided capture symptoms: SYN without ACK, lost segments, ICMP-in-tunnel. It is categorised as a Read tool in the PacketMaster MCP Server, which means it retrieves data without modifying state.
Register the PacketMaster MCP server in PolicyLayer and add a rule for pm_asymmetric_hints: 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 PacketMaster. Nothing to install.
pm_asymmetric_hints 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 pm_asymmetric_hints 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 pm_asymmetric_hints. 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.
pm_asymmetric_hints is provided by the PacketMaster MCP server (jctechbr/packetmaster). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
