Get information about all threads (DAP standard)
AI agents call threads 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 retrieves diagnostic information about active threads in a debugging session. It has no side effects, does not execute code, modify data, or trigger external operations. While part of a debugger interface (which can be powerful), the 'threads' operation itself is purely informational.
From the tool's definition Tool name 'threads' and description 'Get information about all threads (DAP standard)' indicate a read-only query operation that retrieves thread state information from a running Node.js debugger without modifying, executing, or deleting anything.
Attacks that exploit this kind of access
Get information about all threads (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 threads: 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.
threads 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 threads 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 threads. 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.
threads 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.
