Why analyze_distinct_words needs a policy

This tool retrieves and processes textual data to generate frequency statistics, which is a read-only operation with no side effects, no code execution, and no data modification or deletion. The blast radius of misuse is minimal—an attacker cannot compromise systems, steal credentials, or alter data through this analysis function.

From the tool's definition Tool is described as analyzing text to 'count distinct words' and 'show their frequency' — purely informational operations with no modification, deletion, or execution capabilities.

POLICY

How to control analyze_distinct_words

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

policy.json

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

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