What inspect_object does on Js Reverse
AI agents call inspect_object to retrieve information from Js Reverse without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why inspect_object is rated Low
The tool only reads and displays information about JavaScript objects without modifying, executing code, deleting data, or triggering external operations. While it operates within a browser control context (Chrome DevTools Protocol), the specific function here is purely introspective. The low severity reflects that object inspection alone cannot cause harm — it merely retrieves information about existing state.
From the tool's definition Tool description explicitly states it 'Deeply inspects a JavaScript object, showing its properties, prototype chain, and methods' — a passive inspection operation with 'no side effects' that retrieves data about object structure.
Attacks that exploit this kind of access
The rule that runs inspect_object safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Js Reverse, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For inspect_object, this is the rule to start with:
inspect_object 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 Js Reverse, apply this rule, and every inspect_object call is checked against it from then on.
Questions about inspect_object
Deeply inspects a JavaScript object, showing its properties, prototype chain, and methods. Useful for understanding object structure. It is categorised as a Read tool in the Js Reverse MCP Server, which means it retrieves data without modifying state.
Register the Js Reverse MCP server in PolicyLayer and add a rule for inspect_object: 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 Js Reverse. Nothing to install.
inspect_object 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 inspect_object 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 inspect_object. 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.
inspect_object is provided by the Js Reverse MCP server (1600822305/js-reverse-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
