AI agents call array_rotate to retrieve information from TinyFn without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
items | string | Yes | Comma-separated items |
positions | integer | Yes | Positions to rotate (positive=right, negative=left) |
Parameters from the server's own tool schema.
This tool performs a deterministic in-memory operation on an array, returning a rotated version. It reads input and produces output without modifying external state, making it a Read/compute operation with minimal risk.
From the tool's definition 'Rotate an array by n positions' — pure transformation/computation on input data with no side effects
Attacks that exploit this kind of access
Rotate an array by n positions. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
array_rotate accepts 2 parameters: items, positions. Required: items, positions. The full parameter table on this page comes from the server's own tool schema.
Register the TinyFn MCP server in PolicyLayer and add a rule for array_rotate: 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 TinyFn. Nothing to install.
array_rotate 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 array_rotate 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 array_rotate. 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.
array_rotate is provided by the TinyFn MCP server (https://api.tinyfn.io/mcp/all/). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
array_rotate is one line of TinyFn's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
