AI agents invoke raw_tcp_exchange to trigger actions in Allcanuse. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
The name implies establishing raw TCP connections and exchanging data with external endpoints, which constitutes executing external network operations. This could be used to communicate with arbitrary hosts, exfiltrate data, or interact with network services. Severity is high due to potential for network-based attacks or data exfiltration, but confidence is reduced because the description is empty.
From the tool's definition Tool name 'raw_tcp_exchange' suggests sending/receiving raw TCP data to arbitrary hosts; description is empty and uninformative.
Documented attack patterns abuse exactly the kind of access raw_tcp_exchange gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Allcanuse, and nothing reaches the server without passing your rules. This is the rule we recommend for raw_tcp_exchange:
{
"version": "1",
"default": "deny",
"tools": {
"raw_tcp_exchange": {
"limits": [
{
"counter": "raw_tcp_exchange_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}raw_tcp_exchange stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
Free to start. No card required.
raw_tcp_exchange. It is categorised as a Execute tool in the Allcanuse MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Allcanuse MCP server in PolicyLayer and add a rule for raw_tcp_exchange: 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 Allcanuse. Nothing to install.
raw_tcp_exchange is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the raw_tcp_exchange 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 raw_tcp_exchange. 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.
raw_tcp_exchange is provided by the Allcanuse MCP server (ra1nyxin/allcanuse-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Allcanuse, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
