AI agents call hypotenuse 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 |
|---|---|---|---|
a | number | Yes | Length of side a |
b | number | Yes | Length of side b |
Parameters from the server's own tool schema.
This is a pure computational tool that retrieves a calculated result based on input parameters (triangle sides). It performs no data modification, execution of arbitrary code, deletion, or financial operations. It fits the Read category as a mathematical operation that returns information without causing side effects.
From the tool's definition The tool 'hypotenuse' calculates the hypotenuse of a right triangle, which is a deterministic mathematical computation with no side effects, state changes, or external operations.
Attacks that exploit this kind of access
Calculate the hypotenuse of a right triangle. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
hypotenuse accepts 2 parameters: a, b. Required: a, b. 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 hypotenuse: 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.
hypotenuse 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 hypotenuse 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 hypotenuse. 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.
hypotenuse 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.
hypotenuse 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.
