CQin04/dsh-playwright-mcp

Category Browser & Web Added 2026-11-10

Configuration bundle that connects Microsoft's official @playwright/mcp to your running Chrome through the Playwright extension, so the agent can drive your logged-in tabs. Install from a local copy: put your extension token in cordis.patch.yml first (with the token, connections skip the extension's approval prompt, so keep it private). Needs Node.js and the Playwright Chrome extension; the default command is the Windows form (cmd.exe /c npx), so change it to npx on macOS or Linux. It starts @playwright/mcp@latest through npx.

Install

# from GitHub (first run asks for allowBuilds approval — follow the hint, retry)

dsh plugin --profile web add github:CQin04/dsh-playwright-mcp

Any plugin you install runs third-party code with your own permissions — it can read your files, use your credentials, and reach the network, and tool approvals don’t sandbox it. GitHub-sourced plugins also run build scripts at install time — pnpm blocks those until you allow them, so an install can stop with ERR_PNPM_GIT_DEP_PREPARE_NOT_ALLOWED or ERR_PNPM_IGNORED_BUILDS; dsh prints the exact key to add under allowBuilds in your profile’s pnpm-workspace.yaml, and the install works on the next run. Allowing a build is a trust decision: only install sources you trust, and pin a commit (github:owner/repo#sha).
