AI agents call list_tags_for_resource to retrieve information from Amazon Redshift MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata (tags) associated with a resource without creating, modifying, deleting, or executing any operations. It is a pure read operation with no side effects. Severity is low because exposing tag listings presents minimal security risk—tags are typically metadata used for organization and cost allocation, not sensitive operational data in most cases.
From the tool's definition Tool name is 'list_tags_for_resource' and description states 'List tags for a resource.' The verb 'list' and action of reading tags without modification indicates a read-only query operation.

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 list_tags_for_resource:
{
"version": "1",
"default": "deny",
"tools": {
"list_tags_for_resource": {}
}
} list_tags_for_resource is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
List tags for a resource. It is categorised as a Read tool in the Amazon Redshift MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Amazon Redshift MCP Server MCP server in PolicyLayer and add a rule for list_tags_for_resource: 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.
list_tags_for_resource is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_tags_for_resource 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 list_tags_for_resource. 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.
list_tags_for_resource 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.
Free to start. No card required.
