Get system information.
AI agents call get_system_info to retrieve information from FastMCP Multi-Tool Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves system metadata without modifying, executing code, or deleting anything. It is a straightforward Read operation. Severity is low because system information is typically non-sensitive in isolation and harmless to expose.
From the tool's definition Tool name is 'get_system_info' and description states 'Get system information.' The verb 'get' and the read-only nature of retrieving system information (CPU, memory, OS details, etc.) indicate a query operation with no side effects.

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 FastMCP Multi-Tool Server MCP server (rt0120-ramco/mcp-py). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
