When to use browser_delete_cookies
Use browser_delete_cookies when you need to read, set, or clear cookies to manage session state.

}Frequently Asked Questions
What does browser_delete_cookies do?
Delete cookies from the browser context. Can delete all cookies, cookies for a specific URL, or a specific cookie by name. Useful for testing login flows or clearing session state. It belongs to Owl Browser's Cookie Management category and is available through the REST API, the Python SDK (browser.delete_cookies()), the Node.js SDK, and the MCP server.
What parameters does browser_delete_cookies accept?
browser_delete_cookies accepts 1 required parameter (context_id) and 2 optional parameters. All parameters are sent as JSON in a POST request to /api/execute/browser_delete_cookies.
Is browser_delete_cookies detectable by anti-bot systems like Cloudflare or DataDome?
No. browser_delete_cookies executes inside Owl Browser's Chromium engine, which applies fingerprint spoofing at the C++ source level rather than through JavaScript patches. Every tool call shares the same consistent, human-like fingerprint, so anti-bot systems such as Cloudflare, DataDome, and Akamai see an ordinary browser.
