What gcd_lcm_calc does on UnClick
AI agents call gcd_lcm_calc 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 |
|---|---|---|---|
a | number | — | First integer. |
b | number | — | Second integer. |
numbers | string | — | Comma-separated integers (or use a and b). |
Parameters from the server's own tool schema.
Why gcd_lcm_calc is rated Low
This tool performs a stateless mathematical calculation (Greatest Common Divisor and Least Common Multiple). It takes numeric inputs and returns computed values. There are no side effects, no data modification, no code execution, no destructive actions, and no financial implications. It is a simple read-like operation in the sense that it queries a mathematical function and returns results.
From the tool's definition Tool name 'gcd_lcm_calc' and description 'Calculate GCD and LCM of two or more integers' indicate a pure mathematical computation that retrieves calculated results without modifying any data or triggering external operations.
Attacks that exploit this kind of access
The rule that runs gcd_lcm_calc 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 gcd_lcm_calc, this is the rule to start with:
gcd_lcm_calc 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 gcd_lcm_calc call is checked against it from then on.
Questions about gcd_lcm_calc
Calculate GCD and LCM of two or more integers. It is categorised as a Read tool in the UnClick MCP Server, which means it retrieves data without modifying state.
gcd_lcm_calc accepts 3 parameters: a, b, numbers. 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 gcd_lcm_calc: 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.
gcd_lcm_calc 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 gcd_lcm_calc 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 gcd_lcm_calc. 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.
gcd_lcm_calc 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.
