Return capinfos metadata and optional SHA-256 hash for a PCAP file.
AI agents call pm_file_info 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 retrieves and queries metadata about PCAP files (via capinfos) and optionally computes a hash digest. These are read-only operations with no side effects, data modification, code execution, or destructive actions. The tool enables analysis and verification of file properties but does not alter or execute anything.
From the tool's definition Tool returns capinfos metadata and optional SHA-256 hash for a PCAP file. The description indicates retrieval of file information and checksums without modification or execution.
Attacks that exploit this kind of access
Return capinfos metadata and optional SHA-256 hash for a PCAP file. 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_file_info: 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_file_info 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_file_info 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_file_info. 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_file_info 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.
