AI agents call conversations to retrieve information from SharkMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes network conversation metadata from packet captures—a read operation with no data modification. However, severity is elevated to 'medium' rather than 'low' because network traffic data can reveal sensitive information (credentials, API keys, personal communications) if an AI agent queries PCAP files containing production or user traffic.
From the tool's definition Tool name 'conversations' on a Wireshark packet analysis server (SharkMCP) suggests querying network conversation data from PCAP files.
Documented attack patterns abuse exactly the kind of access conversations gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SharkMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for conversations:
{
"version": "1",
"default": "deny",
"tools": {
"conversations": {}
}
}conversations is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

conversations. It is categorised as a Read tool in the SharkMCP MCP Server, which means it retrieves data without modifying state.
Register the Shark MCP server in PolicyLayer and add a rule for conversations: 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 SharkMCP. Nothing to install.
conversations 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 conversations 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 conversations. 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.
conversations is provided by the Shark MCP server (weirdmachine64/sharkmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
