WHAT IT DOES

What text_truncate does on UnClick

AI agents call text_truncate 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
`text`	string	Yes
`suffix`	string	—
`max_length`	number	Yes

Parameters from the server's own tool schema.

RISK

Why text_truncate is rated Low

This tool performs a purely computational/transformation operation on input text — shortening it to a specified length. It has no side effects, does not modify external data, and is fully reversible in the sense that no data is destroyed externally. It is essentially a text processing utility with minimal risk.

RECOMMENDED RULE

The rule that runs text_truncate 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 text_truncate, this is the rule to start with:

text_truncate Allowed

text_truncate 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_truncate": {}
  }
}

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 text_truncate call is checked against it from then on.
