AI agents use CreateCodeConnection 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 'Create' verb clearly indicates a Write operation that modifies state by establishing a new connection resource. While the empty description limits certainty, the naming convention and server context (AWS/Redshift) strongly suggest this creates a reversible connection configuration rather than executing queries or deleting resources.
From the tool's definition Tool name 'CreateCodeConnection' indicates a creation operation (Write). The Amazon Redshift context and AWS Labs MCP server suggest this likely creates or establishes a code connection resource for Redshift.
Documented attack patterns abuse exactly the kind of access CreateCodeConnection 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 CreateCodeConnection:
{
"version": "1",
"default": "deny",
"tools": {
"CreateCodeConnection": {
"limits": [
{
"counter": "createcodeconnection_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}CreateCodeConnection 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.

CreateCodeConnection. 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 CreateCodeConnection: 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.
CreateCodeConnection 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 CreateCodeConnection 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 CreateCodeConnection. 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.
CreateCodeConnection 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.
