chromedevtoolsmcp-mcp — Claude Code MCP server: setup guide
A hosted DevTools MCP server that gives coding agents structured access to browser console errors, page state, and network waterfalls.
claude mcp add --transport http chromedevtoolsmcp-mcp https://chromedevtoolsmcp.clauxel.com/mcpWhat chromedevtoolsmcp-mcp 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.
What it helps with
- 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 for the agent
- 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.
