CDP FAQs

Question 1

What are the requirements to use CDP?

Accepted Answer

To run the CDP MCP server, you'll need the Bun runtime installed on your system and Google Chrome (macOS currently) available. Once set up, Chrome will automatically launch when Claude Code uses any of the CDP tools.

Question 2

How does CDP differ from Claude Code's built-in WebSearch or WebFetch?

Accepted Answer

While WebSearch is read-only and fetches static content, CDP provides full browser control. CDP renders JavaScript, handles session-aware interactions (logins, persistent cookies), allows clicks, typing, scrolling, and can capture visual screenshots, making it ideal for interactive and dynamic websites that WebSearch cannot handle.

Question 3

What kind of tasks can I automate with CDP using Claude Code?

Accepted Answer

You can automate a wide range of tasks, including navigating to URLs, extracting specific data from tables or elements, filling out and submitting forms, clicking buttons, scrolling pages, taking full-page or element screenshots, downloading files (e.g., PDF reports), and even executing arbitrary JavaScript on a page.

Question 4

Can CDP handle dynamic websites (SPAs) and user logins?

Accepted Answer

Yes, absolutely. CDP renders JavaScript, allowing it to fully interact with modern Single-Page Applications (SPAs) like React or Vue websites. It is also session-aware, meaning it can manage cookies, log in to accounts, and access private, authenticated dashboards.

Question 5

What is CDP and what can it do for Claude Code?

Accepted Answer

CDP (Chrome DevTools Protocol) is an MCP server that grants Claude Code full interactive control over a Chrome browser. This enables advanced web automation, data extraction from dynamic sites, form filling, logins, taking screenshots, and downloading files, essentially letting Claude 'see' and 'interact' with the web like a human.
