List all available video capture devices with their index and name. Use this to find the correct HDMI capture device.
AI agents call list_capture_devices 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 enumerates hardware devices and returns metadata (index and name). It performs a read-only query against the system's device configuration. While the broader server enables dangerous capabilities (keyboard/mouse control, screen capture), this specific tool merely retrieves information about available capture devices without modifying state, executing code, or triggering actions.
From the tool's definition Tool name includes 'list' and description states 'List all available video capture devices with their index and name'. The verb 'list' is a retrieval operation with no side effects.
Attacks that exploit this kind of access
List all available video capture devices with their index and name. Use this to find the correct 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 list_capture_devices: 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.
list_capture_devices 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 list_capture_devices 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 list_capture_devices. 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.
list_capture_devices 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.
