WHAT IT DOES

What diff_text does on UnClick

AI agents call diff_text to retrieve information from UnClick without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`text_a`	string	Yes	First text (original).
`text_b`	string	Yes	Second text (modified).

Parameters from the server's own tool schema.

RISK

Why diff_text is rated Low

This is a text comparison/diff utility that analyzes two texts and outputs the differences. No side effects occur—neither input text is modified, no external state changes, and no code execution or deletion happens. The tool only retrieves and displays differential analysis, making it a straightforward Read category operation with minimal risk.

From the tool's definition Tool performs comparison and shows differences without modifying either input text. Keywords: 'Compare', 'show added/removed lines' indicate read-only analysis of data.

RECOMMENDED RULE

The rule that runs diff_text safely

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

diff_text Allowed

diff_text 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": {
    "diff_text": {}
  }
}

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

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