What area_calculate does on UnClick
AI agents call area_calculate to retrieve information from UnClick 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 |
|---|---|---|---|
base | number | — | Base (triangle, parallelogram). |
base1 | number | — | First base (trapezoid). |
base2 | number | — | Second base (trapezoid). |
shape | string | Yes | Shape: circle, rectangle, triangle, trapezoid, ellipse, parallelogram, or sector. |
width | number | — | Width (rectangle). |
height | number | — | Height (rectangle, triangle, trapezoid, parallelogram). |
radius | number | — | Radius (circle, sector). |
semi_major | number | — | Semi-major axis (ellipse). |
semi_minor | number | — | Semi-minor axis (ellipse). |
angle_degrees | number | — | Angle in degrees (sector). |

Why area_calculate is rated Low
This is a pure computational tool that retrieves or calculates mathematical properties based on input parameters. It neither modifies state, executes arbitrary code, destroys data, nor involves financial transactions. The blast radius of misuse is minimal—incorrect area calculations pose no security risk.
From the tool's definition Tool performs calculation of area and perimeter for geometric shapes (circle, rectangle, triangle, trapezoid, ellipse, parallelogram, sector). No side effects mentioned; purely computational return of mathematical results.

Attacks that exploit this kind of access
The rule that runs area_calculate safely
PolicyLayer is an MCP gateway: it sits between your AI agents and UnClick, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For area_calculate, this is the rule to start with:
area_calculate is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect UnClick, apply this rule, and every area_calculate call is checked against it from then on.
Questions about area_calculate
Calculate area (and perimeter where possible) of common shapes: circle, rectangle, triangle, trapezoid, ellipse, parallelogram, sector. It is categorised as a Read tool in the UnClick MCP Server, which means it retrieves data without modifying state.
area_calculate accepts 10 parameters: base, base1, base2, shape, width, height, radius, semi_major, semi_minor, angle_degrees. Required: shape. The full parameter table on this page comes from the server's own tool schema.
Register the UnClick MCP server in PolicyLayer and add a rule for area_calculate: 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 UnClick. Nothing to install.
area_calculate 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 area_calculate 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 area_calculate. 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.
area_calculate is provided by the UnClick MCP server (@unclick/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
