What normal_distribution does on UnClick
AI agents call normal_distribution 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 |
|---|---|---|---|
x | number | Yes | The value to evaluate. |
mean | number | — | Distribution mean (default 0). |
stddev | number | — | Standard deviation (default 1, must be positive). |
Parameters from the server's own tool schema.
Why normal_distribution is rated Low
This is a pure mathematical/statistical computation tool. It reads input parameters and returns calculated results without side effects. No data is created, modified, deleted, or external operations triggered. This aligns with the Read category definition of retrieval or queries with no side effects.
From the tool's definition Tool performs statistical calculations (PDF, CDF, percentile) on normal distribution parameters. No data modification, deletion, code execution, or external state changes occur.
Attacks that exploit this kind of access
The rule that runs normal_distribution 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 normal_distribution, this is the rule to start with:
normal_distribution 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 normal_distribution call is checked against it from then on.
Questions about normal_distribution
Calculate normal (Gaussian) distribution PDF, CDF, and percentile for a given value. It is categorised as a Read tool in the UnClick MCP Server, which means it retrieves data without modifying state.
normal_distribution accepts 3 parameters: x, mean, stddev. Required: x. 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 normal_distribution: 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.
normal_distribution 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 normal_distribution 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 normal_distribution. 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.
normal_distribution 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.
