THE RISK

Why test-migration needs a policy

The description is empty, so there is no reliable information about what this tool does. The name 'test-migration' could imply testing a migration process (Execute/Write) or simply reading/validating migration state (Read). Given the server context (Bedrock Knowledge Base Retrieval), it could relate to migrating knowledge base data, but without a description, confidence is very low.

From the tool's definition Tool name is 'test-migration' but description is empty and uninformative, making classification highly uncertain.

POLICY

How to control test-migration

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 test-migration:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "test-migration": {
      "limits": [
        {
          "counter": "test-migration_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

test-migration gets a rate cap, and everything else on the server is denied unless you say otherwise.

Questions about test-migration

What does the test-migration tool do? +

test-migration. It is categorised as a Other tool in the Amazon Bedrock Knowledge Base Retrieval MCP Server MCP Server, which means it performs auxiliary operations.

How do I enforce a policy on test-migration? +

Register the Amazon Bedrock Knowledge Base Retrieval MCP Server MCP server in PolicyLayer and add a rule for test-migration: 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 test-migration? +
