maintenance_detect_gpu
Detect GPU family from WebGL/WebGPU renderer strings. Classifies into NVIDIA, AMD, Intel, Apple, Mali, Adreno, PowerVR, Vivante, Broadcom, Qualcomm, Microsoft. Pure-TS classifier — no browser needed. Provide at least one of webglRenderer, webgpuDescription, or deviceName.

What maintenance_detect_gpu does on Jshookmcp
AI agents call maintenance_detect_gpu to retrieve information from Jshookmcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why maintenance_detect_gpu is rated Low
Tool analyzes provided strings to classify GPU type without side effects or external operations.
From the tool's definition Detect GPU family from renderer strings. Pure-TS classifier — no browser needed.
Attacks that exploit this kind of access
The rule that runs maintenance_detect_gpu safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Jshookmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For maintenance_detect_gpu, this is the rule to start with:
maintenance_detect_gpu is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Jshookmcp, apply this rule, and every maintenance_detect_gpu call is checked against it from then on.
Questions about maintenance_detect_gpu
Detect GPU family from WebGL/WebGPU renderer strings. Classifies into NVIDIA, AMD, Intel, Apple, Mali, Adreno, PowerVR, Vivante, Broadcom, Qualcomm, Microsoft. Pure-TS classifier — no browser needed. Provide at least one of webglRenderer, webgpuDescription, or deviceName. It is categorised as a Read tool in the Jshookmcp MCP Server, which means it retrieves data without modifying state.
Register the Jshook MCP server in PolicyLayer and add a rule for maintenance_detect_gpu: 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 Jshookmcp. Nothing to install.
maintenance_detect_gpu 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 maintenance_detect_gpu 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 maintenance_detect_gpu. 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.
maintenance_detect_gpu is provided by the Jshook MCP server (@jshookmcp/jshook). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
