## What it does

The service acts as a hosted remote endpoint for browser diagnostics. It equips agents with four structured tools: `inspect_page_state`, `read_console_errors`, `summarize_network_waterfall`, and `export_devtools_receipt` for generating audit proof.

Communication runs over Streamable HTTP at `https://chromedevtoolsmcp.clauxel.com/mcp`. Because this is a commercial hosted offering, all production calls require a bearer token generated on the provider website. Unauthenticated requests return a JSON error.

Without an active paid plan and valid token, agent requests will fail immediately. The public repository acts strictly as directory documentation rather than runnable local server code.

## Requirements
- Remote server: `https://chromedevtoolsmcp.clauxel.com/mcp`
- Works with: Chrome

## When to use it
- inspect browser console errors during agent runs
- summarize network waterfalls for web pages
- export audit receipts from DevTools sessions
- check the runtime state of a target page

## Example prompts
- Read the latest console errors from the active page.
- Summarize the network waterfall and report slow endpoints.
- Export a DevTools session receipt for the test run.
