Summary

  • playwright-cli list --all now detects browsers whose default profile has the Playwright MCP extension installed and prints them in a new "Browsers available to attach via extension" section with a ready-to-copy playwright-cli attach --extension=<channel> command.
  • Detection piggy-backs on the existing channel scan: we additionally check <userDataDir>/Default/Extensions/<extensionId>. Endpoint and extension checks now run in parallel per channel.

@yury-s
feat(cli): merge extension attach info into discovered browsers
eb46996
Instead of a separate "Browsers available to attach via extension"
section, each discovered browser now reports extension status first
(attach command if installed, install URL otherwise), followed by its
current remote debugging status.
@yury-s
feat(cli): compact per-browser attach instructions
6ebd9a4
Each discovered browser now renders two `attach (extension)` / `attach (remote debugging)` lines showing either the ready-to-run `playwright-cli attach` command or the install/enable link. Removes the dead `remoteDebuggingHint` helper.
@yury-s
feat(cli): use edge://inspect for Edge channels
603598c
Edge channels show `edge://inspect/#remote-debugging` instead of the Chrome-only URL when surfacing the remote-debugging enablement hint.

Summary
  • playwright-cli list --all now detects browsers whose default profile has the Playwright MCP extension installed and prints them in a new "Browsers available to attach via extension" section with a ready-to-copy playwright-cli attach --extension=<channel> command.
  • Detection piggy-backs on the existing channel scan: we additionally check <userDataDir>/Default/Extensions/<extensionId>. Endpoint and extension checks now run in parallel per channel.

@yury-s
feat(cli): merge extension attach info into discovered browsers
eb46996
Instead of a separate "Browsers available to attach via extension"
section, each discovered browser now reports extension status first
(attach command if installed, install URL otherwise), followed by its
current remote debugging status.
@yury-s
feat(cli): compact per-browser attach instructions
6ebd9a4
Each discovered browser now renders two `attach (extension)` / `attach (remote debugging)` lines showing either the ready-to-run `playwright-cli attach` command or the install/enable link. Removes the dead `remoteDebuggingHint` helper.
@yury-s
feat(cli): use edge://inspect for Edge channels
603598c
Edge channels show `edge://inspect/#remote-debugging` instead of the Chrome-only URL when surfacing the remote-debugging enablement hint.
