Why mcpretentious-info needs a policy

This tool performs only data retrieval operations on terminal metadata. It does not execute code, modify system state, or trigger external operations. While it provides information about active terminal sessions, the read-only nature and limited scope of metadata querying (dimensions and session info) make this a low-severity Read operation.

From the tool's definition Tool description states it 'Gets terminal metadata including dimensions (columns × rows) and session information' — purely retrieving information with no modification or execution of commands.

POLICY

How to control mcpretentious-info

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "mcpretentious-info": {}
  }
}

mcpretentious-info 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 MCPretentious — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
