Get Cursor client cookie

The cookie from Cursor webpage does not work in Cursor-To-OpenAI server. You need to get the Cursor client cookie following these steps:

1. Run npm install to initialize the environment。
2. Run npm run login. Open the URL shows in the log, and then login your account.
3. The cookie shows in your command is the Curosr Cookie value. Copy and save it to your notepad.

The log of this command looks like:

[Log] Please open the following URL in your browser to login:
https://www.cursor.com/loginDeepControl?challenge=6aDBevuHkK-HLiZ<......>k2lEjbVRMpg&uuid=5147ac09<....>5fe5f3aeb&mode=login      <-- Copy the url and open it in your browser.

API to get Cursor client cookie

We provide an API to save you from manual login. You need to log in to your Cursor account in browser and get WorkosCursorSessionToken from Application-Cookie.

1. Get Cursor client cookie
   • Url：http://localhost:3010/cursor/loginDeepContorl
   • Request：GET
   • Authentication：Bearer Token（The value of WorkosCursorSessionToken from Cursor webpage)
   • Reponse: In JSON, the value of accessToken is the Cursor Cookie in JWT format. That's what you want.

Sample request:

import requests

WorkosCursorSessionToken = "{{{Repalce by your WorkosCursorSessionToken from cookie in browser}}}}"
response = requests.get("http://localhost:3010/cursor/loginDeepControl", headers={
    "authorization": f"Bearer {WorkosCursorSessionToken}"
})
data = response.json()
cookie = data["accessToken"]
print(cookie)
