What json_prettify does on UnClick
AI agents call json_prettify 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 |
|---|---|---|---|
json | string | Yes | JSON text to format. |
indent | number | — | Indent spaces (default 2). |
minify | boolean | — | Minify instead of prettify (default false). |
Parameters from the server's own tool schema.
Why json_prettify is rated Low
This is a formatting utility that reformats JSON strings. It takes JSON input and returns reformatted output without any destructive, financial, or execute operations. There are no external data retrievals (Read would normally exclude such, but this fits the pattern of benign data access), no persistent modifications (Write), no code execution (Execute), no deletions (Destructive), or financial transactions…
From the tool's definition Tool performs "Prettify or minify JSON text" — a pure data transformation operation on provided JSON without retrieving external data, modifying persistent state, executing code, or causing side effects.
Attacks that exploit this kind of access
The rule that runs json_prettify 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 json_prettify, this is the rule to start with:
json_prettify 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 json_prettify call is checked against it from then on.

Register the UnClick MCP server in PolicyLayer and add a rule for json_prettify: 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.
json_prettify 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 json_prettify 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 json_prettify. 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.
json_prettify 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.
