Why update_agent_runtime_endpoint needs a policy

With no description available, classification is highly uncertain. The name suggests modifying a runtime endpoint configuration (a Write operation), but it's anomalous for an Amazon Translate MCP server. Defaulting to Other with low confidence due to insufficient evidence, while noting it could be Write if it modifies endpoint configuration.

From the tool's definition Tool description is empty and uninformative; tool name 'update_agent_runtime_endpoint' does not clearly match the server's stated purpose of Amazon Translate text translation, custom terminology management, and batch translation processing.

POLICY

How to control update_agent_runtime_endpoint

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 update_agent_runtime_endpoint:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "update_agent_runtime_endpoint": {
      "limits": [
        {
          "counter": "update_agent_runtime_endpoint_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

update_agent_runtime_endpoint gets a rate cap, and everything else on the server is denied unless you say otherwise.

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