Connect an MCP-compatible client to the local Playwright MCP server, then ask the agent to open a URL and take a screenshot. The documented setup uses Node.js 20 or newer and starts the server with npx @playwright/mcp@latest. By default, Playwright MCP uses accessibility information to interact with pages; screenshot capture is a separate visual output.
What you need
- Node.js 20 or newer. The Playwright MCP getting-started guide lists this as a prerequisite: Playwright MCP getting started.
- An MCP-compatible client. The guide lists VS Code, Cursor, Windsurf, Claude Code, and Claude Desktop among supported clients. Client setup and MCP configuration file locations differ, so use the instructions for your particular client.
Connect the local Playwright MCP server
- Open your MCP client’s configuration for servers. The exact file and UI path depend on the client.
- Add the following server entry to its MCP configuration, preserving any existing servers and valid JSON syntax:
{ "mcpServers": { "playwright": { "command": "npx", "args": ["@playwright/mcp@latest"] } } }This is the documented lightweight configuration: the client launches Playwright MCP through
npx. See the official Playwright MCP client configuration guide. - Save the configuration, then restart or reload the MCP connection as required by your client. Confirm that the client shows the Playwright server as connected and its browser tools are available.
- In the agent conversation, ask it to navigate to a specific URL and take a screenshot. For example:
Open https://example.com and take a screenshot of the page.The quick reference also uses the request “Take a screenshot of the page.” For site-specific results, state the full URL and whether you want the current viewport or a particular element.
Navigate and capture the page
Playwright MCP exposes browser automation tools over MCP. The ordinary interaction flow is semantic: the agent can inspect an accessibility snapshot containing roles, labels, text, and element references, then use those references to navigate and operate page controls. The screenshot tool captures visual output from the current page; it is not the mechanism the agent must use to locate every element.
Ask the agent to navigate before taking the screenshot, and give it a precise destination. If the page requires a login, is a single-page app, or takes time to render, tell the agent what state should be visible before it captures. Whether the browser can access a logged-in session depends on how the browser and client are configured; do not assume a separate or remote browser shares your normal browser’s cookies.
Run it headlessly or over HTTP
Headless browser
The default browser is headed. For a non-visible run, add --headless to the server arguments:
#1 Best Overall
{
"mcpServers": {
"playwright": {
"command": "npx",
"args": ["@playwright/mcp@latest", "--headless"]
}
}
}Use the headed default when you need to watch browser behavior while diagnosing a workflow. Use headless mode when a visible browser window is not needed.
Separately started HTTP server
Instead of having the client launch a local stdio process, start the documented HTTP server in a terminal:
npx @playwright/mcp@latest --port 8931Configure the client to connect to http://localhost:8931/mcp. This is useful when the server and client need a separate connection arrangement on the same machine. The port option alone does not make the service appropriate to expose publicly.

Accessibility interaction, screenshots, and vision
The core toolset includes navigation, accessibility snapshots, clicks, typing, screenshots, tabs, dialogs, and browser sizing. Most ordinary web interaction uses semantic page information rather than image interpretation. The optional vision capability adds coordinate-based mouse operations and requires a vision-capable language model; enable it only when the agent needs image-driven interaction, such as clicking a target that is difficult to address semantically. See the Playwright MCP capability documentation.

Security and network exposure
Keep the server limited to trusted clients
The local stdio setup is the simplest documented configuration. If you run an HTTP server, think carefully about which interfaces it listens on and which clients can reach it. Binding to 0.0.0.0 makes it reachable on all network interfaces, rather than only through the local loopback interface; apply deliberate network controls before doing so.
Do not treat origin and file controls as isolation
Playwright’s configuration documentation warns: “Origin lists and the file-access guardrail are convenience defenses to catch unintended access, not a security boundary — they do not affect redirects and can be worked around deliberately.” Use client-level permissions for actual isolation; do not rely on these guardrails to contain an untrusted agent or client. Read the complete Playwright MCP configuration security guidance.
Rank #3
Be cautious with arbitrary code execution
The distinct browser_run_code_unsafe tool executes arbitrary JavaScript in the Playwright server process. Playwright describes it as RCE-equivalent and says to enable it only for trusted MCP clients. Do not enable or expose it merely to take ordinary screenshots. See the warning in the Playwright MCP documentation.
MCP or Playwright CLI?
Playwright’s introduction positions MCP for specialized agentic loops and exploratory automation, while its CLI is aimed at coding agents working in large codebases. MCP’s tool schemas and accessibility snapshots consume more context; CLI output is more concise and skills load on demand. The choice is about workflow rather than screenshot quality: use MCP when the agent benefits from a persistent, interactive browser tool connection, and consider the CLI when the coding-agent workflow and lower tool-output overhead better fit. See Playwright’s MCP and CLI overview.

A self-hosted MCP server means you run the server and browser workflow yourself; with the local stdio configuration, the client starts the process. Microsoft’s Playwright Workspaces remote MCP is a managed-browser comparison, but its documentation labels it a preview, says preview features have no SLA, and does not recommend them for production workloads. Treat that maturity caveat as specific to the documented preview, not as a general claim about all hosted browser services. See Microsoft’s Playwright Workspaces MCP documentation.

Troubleshooting
The client does not show Playwright tools
- Check that Node.js is version 20 or newer and available to the process that launches the client.
- Validate the JSON syntax, including commas and quotation marks, and confirm the server key is nested under
mcpServers. - Restart or reload the client’s MCP connection after saving the configuration. Consult the client-specific configuration guide if the server is still absent.
The browser does not appear
The documented default is headed, but a client may run processes in an environment without a visible desktop. Add --headless when a visible browser is not needed. If you expect a window, check the environment and client process rather than assuming the screenshot tool opens a separate window for every capture.
The screenshot shows the wrong or unfinished state
Give the agent the exact URL and describe the desired page state before capture. Ask it to wait for the page or relevant content to load, then take the screenshot. For interactive pages, specify the controls or content that must be visible. A screenshot records the current browser state; it does not by itself ensure that a site has finished loading.
The HTTP client cannot connect
Confirm the server process is still running on port 8931 and that the client uses http://localhost:8931/mcp. If the client is on a different machine, localhost refers to that client machine, not the server; network binding and access controls must be configured deliberately.

A page or local file is reachable despite restrictions
Do not treat origin lists or file-access guardrails as security boundaries: redirects can bypass their intended limits. Restrict the MCP client through its own permissions and control network access to the server.

Cookie banners are accepted and removed before capture, along with supported newsletter popups and chat widgets. Bot checks or CAPTCHAs, blank pages, timeouts, failed loads, and cache hits are not billed; responses identify the page verdict and billing status. An MCP server lets AI agents use its screenshot tools. The free plan includes 1,000 screenshots a month with no card; paid plans start at $5 for 3,000. Sign up for free.
Frequently Asked Questions
Does Playwright MCP need a vision-capable AI model to take a screenshot?
No. Screenshot capture is part of the core toolset. A vision-capable model is required only for the optional coordinate-based vision capability.
Quick Recap
Can Playwright MCP run without showing a browser window?
Yes. Add --headless to the server arguments.
