These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

browser_tabs

List, create, or close browser tabs.

browser_context_info

Describe the shared browser context: all tabs, origins, and a note that cookies/storage are per-origin (localhost vs 127.0.0.1 are different).

browser_navigate

Navigate to a URL in the specified tab. Relative paths like /foo require base_url or PLAYWRIGHT_MCP_BASE_URL.

browser_snapshot

Accessibility snapshot (structured DOM text). Use root_selector to narrow scope; max_chars avoids huge MCP payloads.

browser_take_screenshot

Take a screenshot of the specified tab. Returns a base64 PNG image.

browser_run_code

Run a Playwright JavaScript function against the specified tab.

browser_click

Click an element. Use force:true to bypass actionability checks when overlays block; trial:true to verify hit target without clicking.

browser_type

Type text into a focused or selected input element.

browser_fill_form

Fill multiple form fields at once.

browser_file_upload

Upload one or multiple files in the specified tab.

browser_hover

Hover over an element.

browser_select_option

Select an option in a <select> element.

browser_press_key

Press a keyboard key.

browser_wait_for

Wait for a selector to appear or disappear, or wait for navigation.

browser_evaluate

Execute JavaScript in the page context and return the result.

browser_navigate_back

Navigate back in history.

browser_network_requests

List recent network requests captured for this tab (since tracking started).

browser_console_messages

Get console messages (log, warn, error) from the page.

browser_resize

Resize the browser viewport.

browser_drag

Drag from one element to another.

browser_handle_dialog

Set up handling for the next browser dialog (alert/confirm/prompt).

browser_close

Close the browser entirely and clean up all resources.

browser_install

Install Chromium used by this MCP server.

// known CVEs in dependencies2 high

Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

46/46 tools missing one or more hints — browser_tabs (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); browser_context_info (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); browser_navigate (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +43 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tests exist

No test files found

Add tests that exercise each declared tool.

No eval / new Function

1 eval() or new Function() call — dynamic code execution

Replace eval / Function with explicit parsing or safer alternatives.

Production dependencies are patched

0 critical, 2 high severity in production deps — @modelcontextprotocol/sdk@1.0.0 (high), playwright@1.49.0 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 5 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
