| Best for | - Developers already using Codex CLI/IDE, Claude Code, Claude Desktop, or Cursor who want to drive a local browser
- Automation that needs both DOM-selector work and coordinate interaction on visual surfaces
- Teams wanting a lightweight Python 3.10+ browser automation option using local Chrome/Chromium
- Local workflows that need no external API credentials, including authorized testing and accessibility work
| - Scenarios where an AI assistant needs to actually drive a browser to complete a task
- Web automation testing and end-to-end verification
| - Frontend developers who want AI-assisted web debugging and performance analysis
- Scenarios that need browser automation and performance diagnostics in the same tool
|
|---|
| Not for | - Users expecting built-in site-specific workflows, component-library adaptation, or challenge handling (these live in the client or optional Skills)
- Environments without Chrome/Chromium or without Python 3.10+
- Users who need a cloud-hosted browser or remote execution environment
- Production-critical scenarios that require official vendor support or an SLA
| - Simple static-text scraping (a lightweight scraper is a better fit)
- Environments sensitive to browser resource usage that can't run a full browser engine
| - Cases that only need to scrape page text without performance analysis or complex interaction (a lighter scraping tool is a better fit)
|
|---|
| Required permissions | - Local browser control: open tabs, navigate to any reachable URL, run bounded JavaScript
- Read and write browser Cookies, localStorage, and sessionStorage
- Read and modify request headers, user agent, HTTP cache, and browser permissions
- File upload and download (bounded by DP_MCP_UPLOAD_ROOT and DP_MCP_DOWNLOAD_ROOT), plus screenshot and PDF/MHTML artifact writes (bounded by DP_MCP_SCREENSHOT_ROOT and DP_MCP_ARTIFACT_ROOT)
- Access to authenticated sessions and page content in the local browser
| - Requires installing and running a browser engine (Chromium/Firefox/WebKit) locally or on a server
- browser_navigate can visit any URL; browser_evaluate can run arbitrary JavaScript in the page context
| - Requires a local Chrome browser instance to run
- navigate_page can visit any URL; type_text/fill_form and similar tools can enter arbitrary content into the page
|
|---|
| Risks and side effects | - The local browser may hold authenticated sessions, cookies, downloads, and page data, so mistakes can affect real accounts or production systems
- It can open and interact with any site reachable from the local machine, risking misuse or violation of site terms
- Coordinate-based interaction depends on the model's reading of screenshot coordinates and can click the wrong place, so observe and verify results
- Downloads, uploads, and exported artifacts write to the local file system, so review directories and content boundaries
- DP_NO_SANDBOX=1 disables the Chrome sandbox and should be reserved for restricted container or root environments
- The project is in beta; real browser behavior depends on the local Chrome/Chromium and target sites
| - browser_evaluate executing arbitrary scripts carries risk if a malicious page is visited — restrict to trusted sites or an isolated environment
- Long-running browser instances consume significant memory and CPU
| - Browser automation tools can access and manipulate the content of open pages — use only in a trusted development/test environment
- performance_start_trace and similar tracing tools continuously record browser activity — avoid leaving them running on pages containing sensitive information
