Show connection status and device information for the serial adapter and HDMI capture device.
AI agents call get_device_info to retrieve information from Mcp Serial Hid Kvm without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about the state and properties of connected hardware (serial adapter, HDMI capture device). It performs no side effects, creates no resources, executes no commands, and cannot delete or move data. While the parent server provides execute and control capabilities via sibling tools, this specific tool is purely informational.
From the tool's definition Tool name 'get_device_info' and description 'Show connection status and device information' indicate a read-only query operation that retrieves metadata about devices without modification or execution.
Attacks that exploit this kind of access
Show connection status and device information for the serial adapter and HDMI capture device. It is categorised as a Read tool in the Mcp Serial Hid Kvm MCP Server, which means it retrieves data without modifying state.
Register the Mcp Serial Hid Kvm MCP server in PolicyLayer and add a rule for get_device_info: 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 Mcp Serial Hid Kvm. Nothing to install.
get_device_info 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_device_info 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_device_info. 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_device_info is provided by the Mcp Serial Hid Kvm MCP server (sunasaji/mcp-serial-hid-kvm). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
