AI agents call array_unzip 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 |
|---|---|---|---|
pairs | string | Yes | JSON array of pairs, e.g., [[1,2],[3,4]] |
Parameters from the server's own tool schema.
array_unzip performs a pure computational transformation on an input array—separating paired elements into two distinct arrays. This is a deterministic operation with no ability to modify, delete, or execute external operations. It retrieves/reorganizes data without side effects, fitting the Read category.
From the tool's definition Tool description: "Unzip array of pairs into two arrays." This is a data transformation function that takes structured input and returns reorganized output with no side effects, data deletion, or external operations.
Attacks that exploit this kind of access
Unzip array of pairs into two arrays. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
array_unzip accepts 1 parameter: pairs. Required: pairs. 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_unzip: 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_unzip 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_unzip 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_unzip. 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_unzip 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_unzip 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.
