Analyze GitHub issues (sorted by comments), PRs, and source code to document key technical challenges for building browser automation MCPs with AI agents. Key findings grounded in actual code: - Token explosion from automatic snapshots in input tools (src/tools/input.ts) - Error handling patterns learned from crashes (src/main.ts, src/PageCollector.ts) - WSL2 Chrome discovery issues (src/browser.ts) - Dual-format output implementation (src/formatters/SnapshotFormatter.ts) - Accessibility tree limitations from Puppeteer dependency Sources: Issues ChromeDevTools#131, ChromeDevTools#363, ChromeDevTools#617, ChromeDevTools#635, ChromeDevTools#689, ChromeDevTools#690, ChromeDevTools#709, ChromeDevTools#713, ChromeDevTools#716, ChromeDevTools#726, ChromeDevTools#752 PRs: ChromeDevTools#618, ChromeDevTools#710, ChromeDevTools#744 Commits: f59b4a2, ca0f560, 3fcca02

The idea is to turn formatters into instances and support both text and JSON formatting. The structured content is output if the experimental structured content flag is passed. For now, only the snapshots are returned in a structured way.
