Medium Risk

Why create_api_cache needs a policy

The 'create' prefix signals data/resource creation. Without additional context about what this cache stores or how it integrates with Redshift queries, Write is the most conservative classification. If this cache could be used to execute queries or modify data, severity could be higher, but creation alone suggests medium severity.

From the tool's definition Tool name 'create_api_cache' indicates creation of a cache resource. The description is empty, but the 'create' action is characteristic of Write operations that establish new reversible resources.

POLICY

How to control create_api_cache

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 create_api_cache:

policy.json

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

create_api_cache 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 create_api_cache

What does the create_api_cache tool do? +

create_api_cache. 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 create_api_cache? +

Register the Amazon Redshift MCP Server MCP server in PolicyLayer and add a rule for create_api_cache: 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 create_api_cache? +

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

Can I rate-limit create_api_cache? +

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

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

create_api_cache 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.
