AI agents call get_bios_settings to retrieve information from Cimc without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves BIOS configuration state. It performs no modifications, deletions, code execution, or external operations. The information returned is informational (token names, values) used to support other operations but poses minimal risk on its own. It is purely a read operation.
From the tool's definition Tool name 'get_bios_settings' and description 'Get all current BIOS token values. Returns token names, class names, and current values' — the verb 'Get' and 'Returns' indicate read-only retrieval of configuration data with no modification or side effects.
Attacks that exploit this kind of access
Get all current BIOS token values. Returns token names, class names, and current values needed for set_bios_setting. It is categorised as a Read tool in the Cimc MCP Server, which means it retrieves data without modifying state.
Register the Cimc MCP server in PolicyLayer and add a rule for get_bios_settings: 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 Cimc. Nothing to install.
get_bios_settings 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_bios_settings 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_bios_settings. 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_bios_settings is provided by the Cimc MCP server (schwarztim/cimc-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
