Study for Claude certification inside Claude

What the connector does

Cred Farmer is a remote MCP server at https://credfarmer.com/mcp. These work at once, with no account:

• list_certifications: The four Claude certification exams: items, minutes, pass mark, fee, eligibility and the 7 December 2026 update.
• get_exam_blueprint: The official domains with their weights and the objectives in each.
• get_practice_question and check_practice_answer: Free practice questions, one at a time, graded on our server with a reason for every option.
• get_free_flashcards: Free flashcards for any of the four exams.
• get_mock_exam_link: Links to the free practice exam and the timed mocks on credfarmer.com.

These need a free Cred Farmer account, and Claude asks you to connect the first time you use one:

• start_drill, answer_drill_question, finish_drill: Drills on the full question bank: your missed questions, one objective, one domain or a short sprint.
• get_my_progress and get_next_step: Your readiness, objective mastery and streak, and the drill your results point to next.
• get_study_plan and set_exam_date: Your weekly pace from your exam date.
• get_due_flashcards and rate_flashcard: Your spaced-repetition flashcards.
• get_study_section: The study guide section for one objective.
• enroll_certification: Start studying a certification.

Questions come without their answer. The key and the explanation come back from our server only after you commit an answer, so Claude cannot show you the answer first. Timed mocks and the diagnostic stay on credfarmer.com, where the free practice exams and the timed forms run.

Connect it to Claude

claude.ai and the Claude apps

Cred Farmer is listed in Anthropic’s connector directory. Choose Add to Claude above to open the listing, or search for Cred Farmer in the connector directory inside Claude. You can also add it as a custom connector with the name Cred Farmer and the URL https://credfarmer.com/mcp. On a Team or Enterprise plan an Owner may need to add it for the organisation first.

Claude Code

claude mcp add --transport http cred-farmer https://credfarmer.com/mcp

Then run /mcp in Claude Code to sign in when a tool asks for your account.

Or install the Cred Farmer plugin, which adds the connector together with three skills (an exam coach that asks one question at a time with no hints before you answer, a certification advisor and an objective tutor), eleven commands and two agents that write a progress gap report and a revision sheet. In Claude Code:

/plugin marketplace add wisegoat22/cred-farmer-plugin
/plugin install cred-farmer@cred-farmer

The plugin’s files are public on GitHub at wisegoat22/cred-farmer-plugin. It runs no local code and contains no questions.

Cursor

Add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "cred-farmer": { "url": "https://credfarmer.com/mcp" }
  }
}

VS Code

Add this to .vscode/mcp.json in your workspace:

{
  "servers": {
    "cred-farmer": { "type": "http", "url": "https://credfarmer.com/mcp" }
  }
}

Signing in

When you ask for something that needs your account, Claude shows a Connect button. It opens credfarmer.com, where you sign in with Google, GitHub or Microsoft, or create a free account the same way. A consent page then names the app asking and what it will be able to do. Choose Allow and Claude carries on. You never type a password into Claude.

Once connected, the app 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

Cred Farmer receives the arguments of each tool call, such as a certification code, a question number and the option you chose, and never your conversation with Claude. Drill answers and flashcard ratings are stored on your account like the ones you give on the site, marked as given in Claude, and your Progress page shows how many there are. Mastery counts them; your readiness score is read from timed mocks only. Access tokens last an hour and are renewed by a refresh token that lasts up to 90 days of use. The full detail is in the privacy policy.

Disconnecting

Open Settings and choose Disconnect under Connected apps. Access ends at once, and the answers you already gave stay on your account. Signing out everywhere also disconnects every connected app. You can remove the connector in Claude as well.
