AI agents call cube 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.

Parameters from the server's own tool schema.
This is a deterministic mathematical utility that only reads input and returns a computed result. It matches the 'Read' category as it retrieves/computes data with no side effects. Severity is low because misuse (e.g., feeding wrong inputs) cannot harm systems, data, or users. The tool belongs in a suite of safe utility functions (math, conversion, validation, encoding).
From the tool's definition Tool name 'cube' and description 'Calculate the cube of a number' indicate a pure mathematical computation with no side effects, no state modification, and no external operations triggered.
Attacks that exploit this kind of access
Calculate the cube of a number. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
cube accepts 1 parameter: number. Required: number. 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 cube: 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.
cube 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 cube 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 cube. 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.
cube 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.
cube 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.
