What memory_get_event does on Amazon Bedrock Knowledge Base Retrieval MCP Server

AI agents call memory_get_event 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.

Low Risk

Why memory_get_event needs a policy

The 'get' verb combined with 'event' and 'memory' indicates this tool retrieves or queries stored event data without modifying it. This aligns with the Read category (retrieves data with no side effects). Severity is low because retrieval operations typically have limited blast radius unless the retrieved data itself is highly sensitive—though without a description this cannot be fully assessed.

From the tool's definition Tool name 'memory_get_event' suggests retrieval of event data from memory with 'get' indicating a read operation. The empty description limits confidence.

How to control memory_get_event

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 memory_get_event:

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

memory_get_event 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 Amazon Bedrock Knowledge Base Retrieval 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.
