Why stream_range needs a policy

Without a description, confidence is reduced. However, 'stream_range' appears to be a query/retrieval operation on stream data. The name suggests reading a contiguous portion of a stream rather than writing, executing code, or destructive operations. In the context of an Amazon Translate MCP server, this could relate to reading translation batches or logs.

From the tool's definition Tool name 'stream_range' with empty description. Based on naming convention in streaming/data contexts, likely retrieves a range of data from a stream without modification.

How to control stream_range

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 stream_range:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "stream_range": {}
  }
}

stream_range is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Amazon Translate MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
