AI agents call get_flow_matrix to retrieve information from Tshark without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'get_flow_matrix' tool appears to retrieve or aggregate flow data for analysis purposes—a read-only operation typical of network packet analysis. No modification, execution, destruction, or financial impact is indicated by the name or server context.
From the tool's definition Tool name 'get_flow_matrix' suggests a query operation that retrieves network flow analysis data. Given the server context (TShark network packet analysis) and sibling tools like 'aggregate_flows' and 'analyze_pcap_file', this tool likely queries or generates…
Attacks that exploit this kind of access
get_flow_matrix. It is categorised as a Read tool in the Tshark MCP Server, which means it retrieves data without modifying state.
Register the Tshark MCP server in PolicyLayer and add a rule for get_flow_matrix: 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 Tshark. Nothing to install.
get_flow_matrix 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_flow_matrix 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_flow_matrix. 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_flow_matrix is provided by the Tshark MCP server (ouonet/tshark-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
