Returns system and platform information (OS type, memory, CPU, Node.js version)
AI agents call system_info to retrieve information from Example MCP Server 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 system metadata without creating, modifying, deleting, or executing operations. It is a pure read operation with minimal security risk, as system information is typically non-sensitive baseline diagnostics. The low severity reflects that misuse would only expose publicly available or non-critical system properties.
From the tool's definition The tool 'Returns system and platform information (OS type, memory, CPU, Node.js version)' indicates data retrieval with no modification or side effects. The description explicitly states it returns informational metrics about the host system.

Returns system and platform information (OS type, memory, CPU, Node.js version). It is categorised as a Read tool in the Example MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Example MCP Server MCP server in PolicyLayer and add a rule for 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 Example MCP Server. Nothing to install.
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 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 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.
system_info is provided by the Example MCP Server MCP server (ranjith63812/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
system_info is one line of Example MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
