AI agents call get_protocols to retrieve information from Wireshark MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves a list of supported protocols—informational metadata with no side effects, no code execution, no data modification, and no destructive or financial impact. It is a straightforward Read operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name 'get_protocols' and description '获取支持的协议列表' (get list of supported protocols) indicate retrieval of static protocol information with no modification or execution.
Documented attack patterns abuse exactly the kind of access get_protocols gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Wireshark MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_protocols:
{
"version": "1",
"default": "deny",
"tools": {
"get_protocols": {}
}
}get_protocols is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

获取支持的协议列表. It is categorised as a Read tool in the Wireshark MCP MCP Server, which means it retrieves data without modifying state.
Register the Wireshark MCP server in PolicyLayer and add a rule for get_protocols: 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. Nothing to install.
get_protocols 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 get_protocols 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 get_protocols. 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.
get_protocols is provided by the Wireshark MCP server (jayimu/wireshark_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Wireshark MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
