THE RISK

Low Risk

Why estimate-text-length-difference needs a policy

This tool performs a measurement and comparison operation on text data to identify potential layout issues. It reads input (original and translated text), performs calculations, and returns risk detection results. No side effects occur—no data is modified, deleted, created, or executed. The configurable tolerance parameter is a read-only configuration input.

From the tool's definition Tool description states it 'Compare[s] original and translated text lengths to detect layout risk' with configurable tolerance.

POLICY

How to control estimate-text-length-difference

PolicyLayer is an MCP gateway — it sits between your AI agents and Android Mcp Toolkit, and nothing reaches the server without passing your rules. This is the rule we recommend for estimate-text-length-difference:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "estimate-text-length-difference": {}
  }
}

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

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