AI agents invoke aiSuperResolution to trigger actions in Tencent Cloud COS MCP Server. 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.
This tool performs image processing (super resolution enhancement) on images stored in COS/CI. It triggers an external image processing operation on Tencent Cloud's CI service, transforming/processing image data. It's not a simple read, nor does it destructively delete data, but it executes a processing operation that modifies or produces image output, making Execute the most appropriate category.

Documented attack patterns abuse exactly the kind of access aiSuperResolution gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Tencent Cloud COS MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for aiSuperResolution:
{
"version": "1",
"default": "deny",
"tools": {
"aiSuperResolution": {
"limits": [
{
"counter": "aisuperresolution_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}aiSuperResolution 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.

图片处理-超分辨率. It is categorised as a Execute tool in the Tencent Cloud COS MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Tencent Cloud COS MCP Server MCP server in PolicyLayer and add a rule for aiSuperResolution: 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 Tencent Cloud COS MCP Server. Nothing to install.
aiSuperResolution 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 aiSuperResolution 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 aiSuperResolution. 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.
aiSuperResolution is provided by the Tencent Cloud COS MCP Server MCP server (tencent/cos-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
