ast_transform_beautify
Pretty-print minified or obfuscated JavaScript: re-emit the parsed source with standard 2-space indentation and normalised spacing. Formatting only — the AST is preserved, so program semantics do not change. Unparseable input is returned unchanged.

What ast_transform_beautify does on Jshookmcp
AI agents call ast_transform_beautify to retrieve information from Jshookmcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why ast_transform_beautify is rated Low
Tool only reformats JavaScript text; no data is written or executed.
From the tool's definition Formatting only — AST is preserved, program semantics do not change

The rule that runs ast_transform_beautify safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Jshookmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For ast_transform_beautify, this is the rule to start with:
ast_transform_beautify 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 Jshookmcp, apply this rule, and every ast_transform_beautify call is checked against it from then on.
