THE RISK

Low Risk

Why get_profile needs a policy

This tool only queries and retrieves existing profile data from a LINE user account. It performs no creation, modification, deletion, or execution of commands. While it accesses personal information, the read-only nature and limited scope to publicly-accessible profile fields (typical for messaging platforms) classify it as a Read operation with low severity.

From the tool's definition Tool is named 'get_profile' and described as 'Get detailed profile information' with no modification or execution capabilities mentioned. It retrieves user data (display name, profile picture URL, status message, language) without side effects.

POLICY

How to control get_profile

PolicyLayer is an MCP gateway — it sits between your AI agents and Line Bot, and nothing reaches the server without passing your rules. This is the rule we recommend for get_profile:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_profile": {}
  }
}

get_profile 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 Line Bot — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
