Create a new Timestream for InfluxDB database cluster.
AI agents use CreateDbCluster to create or update resources in Amazon Redshift MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Amazon Redshift MCP Server environment.
This tool creates infrastructure and persistent resources (a database cluster) but does not permanently destroy data or move money. Resource creation is a Write operation. Severity is high because creating database clusters commits infrastructure resources and could incur significant AWS costs, though the operation is technically reversible through deletion.
From the tool's definition CreateDbCluster creates a new database cluster; the description states 'Create a new Timestream for InfluxDB database cluster' which is a reversible resource creation operation.
Documented attack patterns abuse exactly the kind of access CreateDbCluster gives an agent:
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 CreateDbCluster:
{
"version": "1",
"default": "deny",
"tools": {
"CreateDbCluster": {
"limits": [
{
"counter": "createdbcluster_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}CreateDbCluster 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 new Timestream for InfluxDB database cluster. 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.
Register the Amazon Redshift MCP Server MCP server in PolicyLayer and add a rule for CreateDbCluster: 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.
CreateDbCluster is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the CreateDbCluster 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.
Set action: deny in the PolicyLayer policy for CreateDbCluster. 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.
CreateDbCluster 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.
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.
