Cred Farmer for ChatGPT
Prepare for a Claude certification from ChatGPT
Cred Farmer works inside ChatGPT through the same server it uses for Claude. Ask about a Claude certification exam, answer free practice questions one at a time, and after you connect a free account, run drills on the full question bank and follow your progress in the chat.
What it does in ChatGPT
These work straight away, signed out:
- Exam facts: Items, minutes, pass mark, fee and eligibility for CCAO-F, CCDV-F, CCAR-F and CCAR-P, and the 7 December 2026 update.
- Blueprints: Each exam’s official domains, their weights and the objectives inside them.
- Free practice questions: One at a time, graded on the Cred Farmer server, with a reason for every option.
- Free flashcards: Up to ten cards per request for any of the four exams.
- Mock exam links: The free no-account practice exam and the timed mocks, which you take on credfarmer.com.
These need a free Cred Farmer account:
- Drills on the full question bank: Your missed questions, one objective, one domain or a short mixed sprint, scored when you finish.
- Your progress: Readiness and the gate that limits it, mastery by objective, and the drill your results point to next.
- Your study plan: Your weekly pace, worked out from the exam date you set.
- Your flashcards: The cards due today, with your recall rating saved for the next review.
- Study guide sections: The Cred Farmer guide text for any one objective.
Every question reaches ChatGPT without its answer. Our server returns the key and the explanation only once an answer is committed, so the assistant has nothing to give away first. Timed mocks and the diagnostic run on credfarmer.com, next to the free practice exams.
Add it to ChatGPT
Cred Farmer has been prepared for ChatGPT’s app directory and is not listed there yet. Until it is, on ChatGPT plans that allow developer mode you can add it yourself: turn on developer mode in ChatGPT’s settings, create an app, and enter the name Cred Farmer, the MCP server URL https://credfarmer.com/mcp and OAuth as the sign-in method. ChatGPT’s menus change from time to time, so follow its own help if a label differs.
The same server also works in Claude, Claude Code, Cursor and VS Code. See Cred Farmer for Claude.
Connecting your account
The first time you ask for a drill, your progress or your flashcards, ChatGPT offers to connect Cred Farmer. That opens credfarmer.com, where you sign in with Google, GitHub or Microsoft, or create a free account the same way. A consent page names ChatGPT and lists what it will be able to do. Choose Allow and you return to the chat. You never give ChatGPT your password.
Once connected, ChatGPT can:
- Run drills from the full question bank and record your answers
- Show your progress, readiness, streak and study plan
- Review your flashcards
- Set your exam date and weekly goal
It cannot:
- See or change your email settings
- Delete your account or change account settings
- Open organisation pages or anything an organisation can see
- Read your conversation: it receives only the tool calls the assistant makes
What Cred Farmer receives and keeps
For each tool call, Cred Farmer receives its arguments, for example a certification code, a question number and your chosen option, and never your ChatGPT conversation. Drill answers and flashcard ratings are saved to your account, marked as given in ChatGPT, and counted on your Progress page. Mastery counts them; readiness is read from timed mocks only. An access token lasts one hour and a refresh token renews it for up to 90 days of use. The privacy policy has the full detail.
Disconnecting
In Settings, choose Disconnect next to ChatGPT under Connected apps. Access stops immediately and the answers you gave stay on your account. Signing out everywhere disconnects every connected app, and you can remove the app in ChatGPT as well.
Frequently asked
Quick answers to the follow-up questions.
Is Cred Farmer in the ChatGPT app directory?
Not yet. It has been prepared for OpenAI’s app review. Until it is listed, you can add it in ChatGPT’s developer mode with the server URL on this page, on plans that allow developer mode.
Do I need a Cred Farmer account to use it in ChatGPT?
Not for exam facts, blueprints, free practice questions or free flashcards. Drills, progress, flashcard reviews and the study plan need a free Cred Farmer account, and ChatGPT asks you to connect it the first time you ask for one of them.
Can Cred Farmer see my ChatGPT chats?
No. Cred Farmer receives the arguments of each tool call ChatGPT makes, such as a certification code and the option you chose. It never receives your conversation.
Do answers I give in ChatGPT count?
Drill answers given in ChatGPT count toward your objective mastery, as drills on the site do, and your Progress page shows how many there are. Your readiness score is read only from timed mocks on credfarmer.com, and work in ChatGPT is not a streak day.
This is a Claude certification. Why use it from ChatGPT?
Because many people study wherever they already chat. The exams are Anthropic’s, and Cred Farmer is independent of both Anthropic and OpenAI. The questions, keys and progress come from Cred Farmer’s server, not from the assistant.
How do I disconnect ChatGPT?
Open Settings on credfarmer.com and choose Disconnect next to ChatGPT under Connected apps. Access ends at once. Signing out everywhere disconnects every connected app, and you can also remove the app in ChatGPT.
