identity_get_resource_policy

WHAT IT DOES

What identity_get_resource_policy does on Amazon Bedrock Knowledge Base Retrieval MCP Server

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

THE RISK

Low Risk

Why identity_get_resource_policy needs a policy

The tool appears designed to retrieve IAM resource policies (a read operation). However, confidence is moderate (0.7) rather than high because the description is empty, leaving ambiguity about exact behavior. The sibling tools suggest this server handles AWS identity and access management operations.

From the tool's definition Tool name 'identity_get_resource_policy' indicates retrieval of an identity/policy document. The 'get' verb and 'resource_policy' object suggest a read operation that queries existing policy configuration rather than modifying or executing actions.

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

POLICY

How to control identity_get_resource_policy

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 identity_get_resource_policy:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "identity_get_resource_policy": {}
  }
}

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

FAQ

Questions about identity_get_resource_policy

What does the identity_get_resource_policy tool do? +

identity_get_resource_policy. It is categorised as a Read tool in the Amazon Bedrock Knowledge Base Retrieval MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on identity_get_resource_policy? +

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

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

Can I rate-limit identity_get_resource_policy? +

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

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

identity_get_resource_policy 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.
