Paul Irish	b747f9d74a	feat: Integrate CrUX data into performance trace summaries (#733 ) We upgrade the performance trace tools to include real-user experience data from the Chrome User Experience Report (CrUX). https://developer.chrome.com/docs/crux https://developer.chrome.com/docs/crux/methodology ### Deets * When a trace is stopped, the server now extracts the primary navigation URLs from the trace (determined by insightSets). * It calls the public CrUX API to fetch field metrics (LCP, INP, CLS) for each unique URL/Origin. * The formatting of crux data is handled by upstream TraceFormatter, but it looks like this: ```md Metrics (field / real users): - LCP: 2595 ms (scope: url) - LCP breakdown: - TTFB: 1273 ms (scope: url) - Load delay: 86 ms (scope: url) - Load duration: 451 ms (scope: url) - Render delay: 786 ms (scope: url) - INP: 140 ms (scope: url) - CLS: 0.06 (scope: url) - The above data is from CrUX–Chrome User Experience Report. It's how the page performs for real users. - The values shown above are the p75 measure of all real Chrome users - The scope indicates if the data came from the entire origin, or a specific url - Lab metrics describe how this specific page load performed, while field metrics are an aggregation of results from real-world users. Best practice is to prioritize metrics that are bad in field data. Lab metrics may be better or worse than fields metrics depending on the developer's machine, network, or the actions performed while tracing. ``` Privacy Considerations: * Updates the server README to inform users that performance analysis tools may send trace URLs to the Google CrUX API. * Adds a notification message to the server startup logs regarding the CrUX API interaction.

Jack Franklin	2d4484a123	fix: ordering of information in performance trace summary (#334 ) Fixes a bug where the output contained "this is a high level summary" before then outputting the call frame / network format information before then outputting the trace summary. With this commit, we now output the summary & insights before ending with the format information.	2025-10-10 12:52:16 +00:00

Jack Franklin	2dbdd2de4f	chore: roll latest chrome-devtools-frontend (#163 ) This includes a better fix for the circular dependency problem and makes the changes in the MCP server based on the upstream DevTools implementation changes.	2025-09-26 09:44:03 +01:00
Jack Franklin	b2e1e3944c	fix: roll latest DevTools to handle Insight errors (#149 ) This commit updates DevTools to the latest release. This most importantly includes a fix for #124 and other reported issues where Insights that were actually errors were not handled correctly. They are now formatted correctly on the DevTools side and now will not break performance traces in the MCP server.	2025-09-25 18:25:35 +02:00
Jack Franklin	e8fb30c1bf	fix: rework performance parsing & error handling (#75 ) This PR tidies up the code around performance parsing and what we respond with from our tools. It introduces the ability to have no Insights from a trace (relatively rare, but can happen), and also adds more information to the output in the event that something went wrong. Previously we just logged errors, but if we respond with them here that will also help users report issues and increase the chances that we can debug them.	2025-09-23 15:42:35 +02:00
