Gets the JavaScript call stack that initiated a network request. This helps trace which code triggered an API call.
AI agents call get_request_initiator to retrieve information from JS Reverse MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and reports existing debugging information (call stack trace) about network request origins. It performs no side effects, does not modify application state, and does not execute arbitrary code or trigger external operations. This is consistent with Read category tools (search, list, get, fetch) that retrieve data for inspection and analysis purposes.
From the tool's definition Tool 'gets' the call stack information that 'initiated' a network request. This is a retrieval operation that queries runtime state without modifying data or executing new code. The description indicates it 'helps trace' — a passive analysis activity.
Attacks that exploit this kind of access
Gets the JavaScript call stack that initiated a network request. This helps trace which code triggered an API call. It is categorised as a Read tool in the JS Reverse MCP MCP Server, which means it retrieves data without modifying state.
Register the JS Reverse MCP server in PolicyLayer and add a rule for get_request_initiator: 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 MCP. Nothing to install.
get_request_initiator 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 get_request_initiator 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 get_request_initiator. 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.
get_request_initiator is provided by the JS Reverse MCP server (zhizhuodemao/js-reverse-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
