Get all loaded source files (DAP standard)
AI agents call loadedSources to retrieve information from MCP Chrome Debugger Protocol without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves information about loaded source files in a Node.js process being debugged. It performs no side effects, does not execute code, does not modify state, and does not delete anything. It is purely informational—a read operation analogous to listing or fetching data.
From the tool's definition Tool name 'loadedSources' and description 'Get all loaded source files' indicate retrieval of metadata about loaded code without modification or execution.
Attacks that exploit this kind of access
Get all loaded source files (DAP standard). It is categorised as a Read tool in the MCP Chrome Debugger Protocol MCP Server, which means it retrieves data without modifying state.
Register the MCP Chrome Debugger Protocol MCP server in PolicyLayer and add a rule for loadedSources: 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 MCP Chrome Debugger Protocol. Nothing to install.
loadedSources 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 loadedSources 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 loadedSources. 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.
loadedSources is provided by the MCP Chrome Debugger Protocol MCP server (vitalyostanin/mcp-chrome-debugger-protocol). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
