List all loaded JavaScript scripts in the current page
AI agents call source_list_scripts to retrieve information from CDP-MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about loaded scripts without executing code, modifying state, or triggering external actions. It is a passive enumeration capability that helps debug and understand what code is running on a page, but does not itself execute or alter anything.
From the tool's definition Tool name 'source_list_scripts' and description 'List all loaded JavaScript scripts in the current page' indicate a query/retrieval operation with no modification or execution capabilities.
Attacks that exploit this kind of access
List all loaded JavaScript scripts in the current page. It is categorised as a Read tool in the CDP-MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CDP-MCP Server MCP server in PolicyLayer and add a rule for source_list_scripts: 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 CDP-MCP Server. Nothing to install.
source_list_scripts 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 source_list_scripts 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 source_list_scripts. 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.
source_list_scripts is provided by the CDP-MCP Server MCP server (jekyll-001/cdp-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
