image_info

Retrieves basic image information, including image format, size, and color model.

How to control image_info ↓

AI agents call image_info to retrieve information from Qiniu MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Low Risk

This tool performs data retrieval only—it fetches and returns image metadata (format, dimensions, color model) from Qiniu Cloud Storage without creating, modifying, deleting, or executing operations. The action is passive introspection of existing data, fitting the 'Read' category with low severity since misuse would only expose image metadata with no capability to alter or harm data.

From the tool's definition Tool name 'image_info' and description 'Retrieves basic image information, including image format, size, and color model' indicate a read-only operation that queries metadata without modification or side effects.

Documented attack patterns abuse exactly the kind of access image_info gives an agent:

PolicyLayer is an MCP gateway — it sits between your AI agents and Qiniu MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for image_info:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "image_info": {}
  }
}

image_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Qiniu MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on image_info? +

Register the Qiniu MCP Server MCP server in PolicyLayer and add a rule for image_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 Qiniu MCP Server. Nothing to install.

What risk level is image_info? +

image_info is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit image_info? +

Yes. Add a rate_limit block to the image_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.

How do I block image_info completely? +

Set action: deny in the PolicyLayer policy for image_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.

What MCP server provides image_info? +

image_info is provided by the Qiniu MCP Server MCP server (qiniu/qiniu-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Qiniu MCP Server tool call.
