AI agents call iograph 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.
Based on server context, 'iograph' appears to generate I/O (input/output) graphs or statistics from captured network traffic—a read-only analytical operation. It extracts and visualizes data from packets without side effects. The empty description limits confidence, but the tool name and server design strongly suggest data retrieval and visualization rather than modification, execution, or destructive operations.
From the tool's definition Tool name 'iograph' suggests I/O graph generation from packet capture data. The server context indicates tools perform packet inspection and analysis (conversations, endpoints, expert_info, io_stats, extract_fields).
Documented attack patterns abuse exactly the kind of access iograph 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 iograph:
{
"version": "1",
"default": "deny",
"tools": {
"iograph": {}
}
}iograph is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

iograph. 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 iograph: 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.
iograph 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 iograph 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 iograph. 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.
iograph 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.
