Newsletter Title

Chrome DevTools MCP 1.12 Can Reload Agent Browser Policy Live

Intro

Chrome DevTools MCP 1.12 can reload URL restrictions and tool settings without a restart, while adding offline heap analysis and parallel page-scoped work.

Takeaways

  • –watchConfig, which watches a JSON configuration file and applies supported changes live; live updates for allowedUrlPattern and blockedUrlPattern; dynamic enablement and disablement…
  • We would watch how teams expose policy changes to operators without exposing them to the agent itself.
