AI agents call get_stream to retrieve information from Packmate without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite the empty description, the tool name and context of a CTF network analyzer indicate this retrieves or queries stream data without side effects. The naming pattern and sibling read operations ('list_*', 'get_packets') support classification as Read.
From the tool's definition Tool name 'get_stream' in a network traffic analyzer context indicates retrieval of stream data. The sibling tools include 'list_streams', 'get_packets', and read-only operations like 'list_patterns' and 'list_services', suggesting this is a query/retrieval…
Attacks that exploit this kind of access
get_stream. It is categorised as a Read tool in the Packmate MCP Server, which means it retrieves data without modifying state.
Register the Packmate MCP server in PolicyLayer and add a rule for get_stream: 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 Packmate. Nothing to install.
get_stream 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_stream 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_stream. 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_stream is provided by the Packmate MCP server (umbra2728/packmate-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
