AI agents call string_get_range to retrieve information from Amazon Translate MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a basic string utility function that extracts a substring from input. It performs no side effects, creates no new resources, executes no code, and cannot delete or modify persistent data. The operation is purely computational and read-only, making it the lowest-risk category.
From the tool's definition Tool name 'string_get_range' and description 'Get substring' indicate a read-only string operation that retrieves a portion of a string without modifying data or triggering external operations.
Documented attack patterns abuse exactly the kind of access string_get_range gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon Translate MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for string_get_range:
{
"version": "1",
"default": "deny",
"tools": {
"string_get_range": {}
}
} string_get_range is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get substring. It is categorised as a Read tool in the Amazon Translate MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Amazon Translate MCP Server MCP server in PolicyLayer and add a rule for string_get_range: 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 Translate MCP Server. Nothing to install.
string_get_range 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 string_get_range 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 string_get_range. 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.
string_get_range is provided by the Amazon Translate MCP Server MCP server (awslabs.amazon-translate-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Amazon Translate MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
