AI agents use gateway_target_create 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.
The tool creates a new gateway target resource, which is a reversible Write operation on AWS Redshift infrastructure. While not destructive, it commits infrastructure changes that could affect data routing and access patterns. High severity due to potential blast radius if misconfigured (e.g., routing data to unintended targets), but not critical since the action is reversible through deletion or modification.
From the tool's definition Tool name 'gateway_target_create' indicates creation of a resource (gateway target) in Redshift; the 'create' verb signals a Write operation that modifies infrastructure state. Description is empty, reducing confidence slightly.
Documented attack patterns abuse exactly the kind of access gateway_target_create 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 gateway_target_create:
{
"version": "1",
"default": "deny",
"tools": {
"gateway_target_create": {
"limits": [
{
"counter": "gateway_target_create_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}gateway_target_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.

gateway_target_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.
Register the Amazon Redshift MCP Server MCP server in PolicyLayer and add a rule for gateway_target_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.
gateway_target_create 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 gateway_target_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.
Set action: deny in the PolicyLayer policy for gateway_target_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.
gateway_target_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.
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.
