Capture console.log / warn / error / info and uncaught exceptions
AI agents call console_messages to retrieve information from Hermes Computer Use without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only reads and captures browser console output (logs, warnings, errors, info, exceptions). It has no side effects and does not modify any data or trigger external operations.

Attacks that exploit this kind of access
Capture console.log / warn / error / info and uncaught exceptions. It is categorised as a Read tool in the Hermes Computer Use MCP Server, which means it retrieves data without modifying state.
Register the Hermes Computer Use MCP server in PolicyLayer and add a rule for console_messages: 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 Hermes Computer Use. Nothing to install.
console_messages 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 console_messages 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 console_messages. 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.
console_messages is provided by the Hermes Computer Use MCP server (noah3521/hermes-computer-use). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
