What frequency_analyse does on UnClick
AI agents call frequency_analyse 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 |
|---|---|---|---|
top | number | — | Number of top entries to return (default 10). |
mode | string | — | 'character' (default) or 'bigram'. |
text | string | Yes | Text to analyse. |
Parameters from the server's own tool schema.
Why frequency_analyse is rated Low
This tool performs statistical text analysis on provided input data. It retrieves and computes frequency information without creating, modifying, deleting, or executing anything. The operation is read-only and non-destructive, with minimal blast radius if misused by an AI agent (e.g., wasting compute on large text samples, but no data loss or side effects).
From the tool's definition Tool description states it 'Analyse character or bigram frequencies in text' — a pure analysis operation with no modification, deletion, or execution of external code.
Attacks that exploit this kind of access
The rule that runs frequency_analyse 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 frequency_analyse, this is the rule to start with:
frequency_analyse 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 frequency_analyse call is checked against it from then on.
Questions about frequency_analyse
Analyse character or bigram frequencies in text. It is categorised as a Read tool in the UnClick MCP Server, which means it retrieves data without modifying state.
frequency_analyse accepts 3 parameters: top, mode, text. Required: text. 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 frequency_analyse: 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.
frequency_analyse 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 frequency_analyse 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 frequency_analyse. 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.
frequency_analyse 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.
