AI agents call get_firmware_versions 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 firmware version information from hardware components. It performs no side effects, creates no modifications, executes no operations, and destroys no data. It is purely informational, making it a Read category tool with low severity since disclosure of firmware versions alone poses minimal risk, though version information could inform targeted attacks in a broader context.
From the tool's definition Tool name 'get_firmware_versions' and description 'List all component firmware versions' indicates a read-only retrieval operation with no modification or execution capabilities.
Attacks that exploit this kind of access
List all component firmware versions: CIMC, BIOS, storage controllers, network adapters, etc. 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_firmware_versions: 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_firmware_versions 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_firmware_versions 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_firmware_versions. 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_firmware_versions 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.
