THE RISK

Why analyze_readability needs a policy

This tool performs read-only analysis of text properties (readability metrics). It retrieves and computes metrics from provided text without creating side effects, modifying data, executing arbitrary code, or affecting external systems. It is a straightforward Read category tool with minimal risk if misused by an AI agent.

From the tool's definition Tool name is 'analyze_readability' and description states it 'Analyze[s] text readability using various metrics' — a pure analysis operation with no modification, deletion, or execution of code/commands.

POLICY

How to control analyze_readability

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

policy.json

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

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