Get FluidNC system information: firmware version, CPU, memory, WiFi, SD card status
AI agents call get_system_info to retrieve information from Cnc Fluidnc without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries system metadata (firmware version, hardware specs, connectivity status, storage info) without modifying any state, executing code, or triggering machine operations. It is a read-only informational tool with minimal security impact if misused by an AI agent.
From the tool's definition Tool name 'get_system_info' and description 'Get FluidNC system information: firmware version, CPU, memory, WiFi, SD card status' indicate retrieval of system information with no modification or execution of commands.
Attacks that exploit this kind of access
Get FluidNC system information: firmware version, CPU, memory, WiFi, SD card status. It is categorised as a Read tool in the Cnc Fluidnc MCP Server, which means it retrieves data without modifying state.
Register the Cnc Fluidnc MCP server in PolicyLayer and add a rule for get_system_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 Cnc Fluidnc. Nothing to install.
get_system_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_system_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_system_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_system_info is provided by the Cnc Fluidnc MCP server (whitneydesignlabs/cnc-fluidnc-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
