What image_scale_2x does on Mcp Hands
AI agents invoke image_scale_2x to trigger actions in Mcp Hands. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why image_scale_2x is rated High
image_scale_2x triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.
Attacks that exploit this kind of access
The rule that runs image_scale_2x safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Hands, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For image_scale_2x, this is the rule to start with:
image_scale_2x stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Hands, apply this rule, and every image_scale_2x call is checked against it from then on.
Questions about image_scale_2x
Upscale an image by a factor with LANCZOS resampling. It is categorised as a Execute tool in the Mcp Hands MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Mcp Hands MCP server in PolicyLayer and add a rule for image_scale_2x: 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 Mcp Hands. Nothing to install.
image_scale_2x is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the image_scale_2x 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 image_scale_2x. 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.
image_scale_2x is provided by the Mcp Hands MCP server (huocai250/mcp-hands). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
