dsh-playwright

One-line value: install this and every DeepSeek Harness agent can drive a real browser — navigation, clicking, typing, snapshots, screenshots — using the official Microsoft Playwright MCP.

DeepSeek Harness profile bundle installing the official Microsoft Playwright MCP (@playwright/mcp) — browser automation through structured accessibility snapshots (no vision model needed), from github.com/microsoft/playwright-mcp. Same bundle pattern as dsh-chrome-devtools.

Capability category: 工具与能力 (Tools & Capabilities) License: MIT · Compatibility: DSH ≥ 0.2.0-rc.2 (bundles API), Windows/macOS/Linux (Node.js + npx + Chrome/Chromium required)

Configuration source: verified via Context7 against the project's own README — the standard client config is exactly:

{ "mcpServers": { "playwright": { "command": "npx", "args": ["@playwright/mcp@latest"] } } }

What it adds to every agent on the profile

Row	Module	Purpose
mcp-playwright	@deepseek-ai/dsh-mcp-client	Spawns npx @playwright/mcp@latest (stdio) → tools namespaced mcp__playwright__*: browser_navigate, browser_snapshot, browser_click, browser_type, browser_take_screenshot, tabs, requests, and more

• Uses your installed Google Chrome by default (headed, persistent profile)
• First start downloads the package via npx (30–60s); afterwards it starts in ~1s
• Coexists with dsh-chrome-devtools — separate tool namespace and browser instance

Install

One command (recommended):

dsh plugin --profile web add github:akash-digitavision/dsh-playwright

or in Settings → Plugin Market (DSH Plugin Hub), search for dsh-playwright.

Manual alternative — add dsh-playwright to the profile package.json dependencies + dsh.profile.bundles, run pnpm install in the profile, restart or re-apply.

Requirements: Node.js ≥ 18 with npx (the MCP server downloads on first use), and an installed Chrome or Chromium.

Note: file: dependencies are copied into the profile by pnpm — after editing this bundle's cordis.patch.yml, run pnpm install again (or edit the installed copy under node_modules\dsh-playwright) before re-applying.

Permissions & external services

• Spawns a local npx @playwright/mcp process that launches a real browser on your machine
• No accounts, no API keys, no telemetry; network access is whatever pages you browse
• Edits/automation run with your user privileges — review prompts before approving destructive actions

Optional launch flags

Append to args in cordis.patch.yml:

Flag	Effect
--isolated	In-memory profile; no persisted cookies/storage
--headless	No visible browser window
--browser chromium	Playwright's bundled Chromium instead of system Chrome
--caps=vision,pdf	Extra capability tools
--config <file.json>	Full JSON configuration (browser, timeouts, network rules, secrets — see project docs)

Verify

Ask the agent to browser_navigate to any page and browser_snapshot it — or check the plugin list for the live include:mcp-playwright entry.

Publish / uninstall

Push this folder to GitHub and install "dsh-playwright": "github:<you>/dsh-playwright". Remove from bundles + dependencies to uninstall; the npx cache can be kept or cleared separately.
