Why memory_create needs a policy

The naming pattern 'memory_create' suggests a write operation that creates new memory or storage entities. Without description details, this cannot be confirmed as Execute (which would require code execution) or Destructive (which would require irreversible deletion). Write is the most reasonable category for a 'create' operation.

From the tool's definition Tool name 'memory_create' suggests creating or storing data. However, the description is empty, making precise classification difficult. The 'create' verb indicates a write operation that generates new data structures, likely reversible.

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

POLICY

How to control memory_create

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

policy.json

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

memory_create 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.

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

FAQ

Questions about memory_create

What does the memory_create tool do? +

memory_create. It is categorised as a Write tool in the Amazon Redshift 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 memory_create? +

Register the Amazon Redshift MCP Server MCP server in PolicyLayer and add a rule for memory_create: 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 Redshift MCP Server. Nothing to install.

What risk level is memory_create? +

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

Can I rate-limit memory_create? +

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

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

memory_create is provided by the Amazon Redshift MCP Server MCP server (awslabs.redshift-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 Amazon Redshift MCP Server tool call.

Start from Amazon Redshift MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
