Decode specific packets with detailed protocol information. Useful for deep packet inspection.
AI agents call tshark_decode to retrieve information from Wireshark MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tshark_decode tool reads and analyzes packet data to extract protocol information. While deep packet inspection could expose sensitive data in plaintext (credentials, PII, keys), the tool itself performs no write, delete, execute, or financial operations. It is fundamentally a Read operation that queries packet contents.
From the tool's definition Tool performs 'Decode specific packets with detailed protocol information' and 'deep packet inspection' — purely analytical operations that retrieve and interpret packet data without modification, capture, or execution of external commands.
Attacks that exploit this kind of access
Decode specific packets with detailed protocol information. Useful for deep packet inspection. It is categorised as a Read tool in the Wireshark MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Wireshark MCP Server MCP server in PolicyLayer and add a rule for tshark_decode: 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 Wireshark MCP Server. Nothing to install.
tshark_decode 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 tshark_decode 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 tshark_decode. 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.
tshark_decode is provided by the Wireshark MCP Server MCP server (schwarztim/sec-wireshark-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
