WHAT IT DOES

What test_host_connection does on 1Panel MCP Server

AI agents invoke test_host_connection to trigger actions in 1Panel MCP Server. 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.

RISK

Why test_host_connection is rated High

Testing a host connection involves executing a network probe/connection attempt to a remote host, which is an active operation with external side effects. It's not purely a read operation since it initiates outbound connections. Misuse could be used to probe internal network resources or validate reachability of unauthorized systems.

From the tool's definition 'Test host connection' - triggers an active network connection attempt to an external host

RECOMMENDED RULE

The rule that runs test_host_connection safely

PolicyLayer is an MCP gateway: it sits between your AI agents and 1Panel MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For test_host_connection, this is the rule to start with:

test_host_connection Rate-limited

test_host_connection 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.
