AI agents call multicast_streams 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 reports statistics about UDP multicast streams from PCAP files. It performs read-only analysis of captured network traffic data—inspecting and calculating statistics on existing multicast stream patterns. No data is created, modified, deleted, or executed.
From the tool's definition Tool name 'multicast_streams' and description 'UDP multicast stream statistics' indicate data retrieval and analysis of network traffic statistics without modification of packet data or network state.
Documented attack patterns abuse exactly the kind of access multicast_streams 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 multicast_streams:
{
"version": "1",
"default": "deny",
"tools": {
"multicast_streams": {}
}
}multicast_streams is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
UDP multicast stream statistics. 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 multicast_streams: 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.
multicast_streams 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 multicast_streams 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 multicast_streams. 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.
multicast_streams 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.
