WHAT IT DOES

What hypotenuse does on TinyFn

AI agents call hypotenuse to retrieve information from TinyFn without modifying anything. It is 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.

RISK

Why hypotenuse is rated Low

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.

RECOMMENDED RULE

The rule that runs hypotenuse safely

PolicyLayer is an MCP gateway: it sits between your AI agents and TinyFn, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For hypotenuse, this is the rule to start with:

hypotenuse Allowed

hypotenuse is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "hypotenuse": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect TinyFn, apply this rule, and every hypotenuse call is checked against it from then on.

FAQ

Questions about hypotenuse

What does the hypotenuse tool do? +

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.

What parameters does hypotenuse accept? +

hypotenuse accepts 2 parameters: a, b. Required: a, b. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on hypotenuse? +

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.

What risk level is hypotenuse? +

hypotenuse is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit hypotenuse? +

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.

How do I block hypotenuse completely? +

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.

What MCP server provides hypotenuse? +

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.
