What title_case does on TinyFn
AI agents call title_case to retrieve information from TinyFn 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 | string | Yes | The text to title case |
Parameters from the server's own tool schema.
Why title_case is rated Low
This tool only reads input text and returns a transformed string. It performs a deterministic formatting operation without creating, modifying, deleting data, executing code, or making financial transactions. It belongs in the Read category as the least risky classification.
From the tool's definition Tool name is 'title_case' and description states 'Convert text to title case.' This is a pure text transformation function with no side effects, data persistence, external calls, or modifications to any state.
Attacks that exploit this kind of access
The rule that runs title_case safely
PolicyLayer is an MCP gateway: it sits between your AI agents and TinyFn, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For title_case, this is the rule to start with:
title_case is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect TinyFn, apply this rule, and every title_case call is checked against it from then on.
