AI agents call text_truncate to retrieve information from UnClick without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
text | string | Yes | |
suffix | string | — | |
max_length | number | Yes |
Parameters from the server's own tool schema.
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.
From the tool's definition Truncate text to a maximum length
Attacks that exploit this kind of access
Truncate text to a maximum length. It is categorised as a Read tool in the UnClick MCP Server, which means it retrieves data without modifying state.
text_truncate accepts 3 parameters: text, suffix, max_length. Required: text, max_length. The full parameter table on this page comes from the server's own tool schema.
Register the UnClick MCP server in PolicyLayer and add a rule for text_truncate: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches UnClick. Nothing to install.
text_truncate is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the text_truncate rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for text_truncate. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
text_truncate is provided by the UnClick MCP server (@unclick/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
