AI agents call get_electron_main_resource_usage to retrieve information from Electron without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only reads and reports resource usage information from the Electron main process. It has no side effects, does not modify state, does not execute arbitrary code, and does not delete or move data. It is a simple monitoring/inspection operation, placing it clearly in the Read category with low severity.
From the tool's definition The tool 'get_electron_main_resource_usage' retrieves 'memory, CPU, OS stats' with 'Compact text output'. It performs a query/inspection of resource metrics without modification or execution of code.
Attacks that exploit this kind of access
Main process resource usage: memory, CPU, OS stats. Compact text output. It is categorised as a Read tool in the Electron MCP Server, which means it retrieves data without modifying state.
Register the Electron MCP server in PolicyLayer and add a rule for get_electron_main_resource_usage: 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 Electron. Nothing to install.
get_electron_main_resource_usage 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_electron_main_resource_usage 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_electron_main_resource_usage. 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_electron_main_resource_usage is provided by the Electron MCP server (ohah/electron-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
