WHAT IT DOES

What copy_image_set does on Amazon Bedrock Knowledge Base Retrieval MCP Server

AI agents use copy_image_set to create or update resources in Amazon Bedrock Knowledge Base Retrieval MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Amazon Bedrock Knowledge Base Retrieval MCP Server environment.

THE RISK

Medium Risk

Why copy_image_set needs a policy

The tool appears to perform a reversible write operation (copying/duplicating an image set), which falls under the Write category. The medium severity reflects that duplicating medical imaging data could have moderate impact (storage costs, data consistency concerns) but is reversible.

From the tool's definition Tool name 'copy_image_set' suggests creating a duplicate of an image set resource. The empty description prevents full certainty of the exact operation, but the 'copy' verb typically indicates a write operation that creates new data.

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

POLICY

How to control copy_image_set

PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon Bedrock Knowledge Base Retrieval MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for copy_image_set:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "copy_image_set": {
      "limits": [
        {
          "counter": "copy_image_set_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

copy_image_set stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about copy_image_set

What does the copy_image_set tool do? +

copy_image_set. It is categorised as a Write tool in the Amazon Bedrock Knowledge Base Retrieval MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on copy_image_set? +

Register the Amazon Bedrock Knowledge Base Retrieval MCP Server MCP server in PolicyLayer and add a rule for copy_image_set: 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 Amazon Bedrock Knowledge Base Retrieval MCP Server. Nothing to install.

What risk level is copy_image_set? +

copy_image_set is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit copy_image_set? +

Yes. Add a rate_limit block to the copy_image_set 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 copy_image_set completely? +

Set action: deny in the PolicyLayer policy for copy_image_set. 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 copy_image_set? +

copy_image_set is provided by the Amazon Bedrock Knowledge Base Retrieval MCP Server MCP server (awslabs.bedrock-kb-retrieval-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
