What fibonacci_sequence does on UnClick
AI agents call fibonacci_sequence 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 |
|---|---|---|---|
n | number | — | How many Fibonacci numbers (1-100, default 10). |
check | number | — | Optional number to test if it is a Fibonacci number. |
Parameters from the server's own tool schema.
Why fibonacci_sequence is rated Low
This tool performs mathematical computation (generating a well-defined mathematical sequence and checking membership) with no side effects. It retrieves or produces computed results without modifying, executing external systems, or affecting financial/destructive operations. This is clearly a Read category tool with minimal risk.
From the tool's definition Tool name 'fibonacci_sequence' and description 'Generate Fibonacci numbers and optionally check if a number is Fibonacci' indicate pure computation with no data modification, deletion, or external operation invocation.
Attacks that exploit this kind of access
The rule that runs fibonacci_sequence 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 fibonacci_sequence, this is the rule to start with:
fibonacci_sequence 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 fibonacci_sequence call is checked against it from then on.
Questions about fibonacci_sequence
Generate Fibonacci numbers and optionally check if a number is Fibonacci. It is categorised as a Read tool in the UnClick MCP Server, which means it retrieves data without modifying state.
fibonacci_sequence accepts 2 parameters: n, check. 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 fibonacci_sequence: 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.
fibonacci_sequence 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 fibonacci_sequence 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 fibonacci_sequence. 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.
fibonacci_sequence 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.
