WHAT IT DOES

What text_metrics does on CoWork OS

RISK

Why text_metrics is rated Low

This tool only analyzes and computes statistics about text — it reads/processes input data and returns metrics with no side effects, no data modification, and no external operations.

RECOMMENDED RULE

The rule that runs text_metrics safely

PolicyLayer is an MCP gateway: it sits between your AI agents and CoWork OS, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For text_metrics, this is the rule to start with:

text_metrics Allowed

text_metrics is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect CoWork OS, apply this rule, and every text_metrics call is checked against it from then on.
