Why modify-replication-group needs a policy

The tool performs a Write operation as it modifies (updates) an existing replication group configuration rather than creating, deleting, or executing arbitrary operations. The empty description lowers confidence slightly, but the clear 'modify' verb in the name strongly indicates a Write category.

From the tool's definition Tool name 'modify-replication-group' indicates modification of a replication group configuration in the context of an SNS/SQS MCP server. The verb 'modify' signifies a reversible change to existing infrastructure.

POLICY

How to control modify-replication-group

PolicyLayer is an MCP gateway — it sits between your AI agents and Awslabs Amazon Sns Sqs, and nothing reaches the server without passing your rules. This is the rule we recommend for modify-replication-group:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "modify-replication-group": {
      "limits": [
        {
          "counter": "modify-replication-group_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

modify-replication-group 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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about modify-replication-group

What does the modify-replication-group tool do? +

modify-replication-group. It is categorised as a Write tool in the Awslabs Amazon Sns Sqs MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on modify-replication-group? +

Register the Awslabs Amazon Sns Sqs MCP server in PolicyLayer and add a rule for modify-replication-group: 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 Awslabs Amazon Sns Sqs. Nothing to install.

What risk level is modify-replication-group? +

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

Can I rate-limit modify-replication-group? +

Yes. Add a rate_limit block to the modify-replication-group 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 modify-replication-group completely? +

Set action: deny in the PolicyLayer policy for modify-replication-group. 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 modify-replication-group? +

modify-replication-group is provided by the Awslabs Amazon Sns Sqs MCP server (awslabs.amazon-sns-sqs-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 Awslabs Amazon Sns Sqs tool call.

Start from Awslabs Amazon Sns Sqs, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
