AI agents call shuffle_list 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 to shuffle |
Parameters from the server's own tool schema.
Shuffling a list is a read-class operation that retrieves and reorders data with no side effects. There are no destructive, financial, or execute-class implications. The tool cannot modify persistent state, delete data, execute code, or trigger external operations. The low severity reflects minimal blast radius even if misused by an AI agent.
From the tool's definition shuffle_list returns a reordered version of an input list. The tool performs a deterministic transformation on data without creating, modifying, deleting, or executing external operations.
Attacks that exploit this kind of access
Shuffle a list of items. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
shuffle_list accepts 1 parameter: items. Required: items. 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 shuffle_list: 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.
shuffle_list 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 shuffle_list 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 shuffle_list. 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.
shuffle_list 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.
shuffle_list 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.
