Use cases

Building a study app? Use data/index.json to list exams and domains to build topic-based study plans.

Comparing certifications? Pull duration_minutes, exam_price_usd, total_questions, and passing_score across vendors.

Tracking your certification path? Use prerequisites to map out dependencies between exams.

Researching exam difficulty? Cross-reference passing_score, total_questions, and duration_minutes.

Grounding an AI assistant or agent? Cert Atlas is clean, factual, source-linked structured data — ideal for RAG / grounding so an LLM can accurately answer "what does the AWS Solutions Architect exam cover?", "what are the CISSP prerequisites?", or "how is CompTIA Security+ weighted by domain?" The site ships an llms.txt manifest, and each index entry carries a practice_url to a matching practice exam.

MCP server

Want agents to query Cert Atlas directly, in context? The mcp/ directory ships a Model Context Protocol server — cert-atlas-mcp — that exposes the dataset to Claude, Cursor, and any MCP client. Read-only, no API key.

cd mcp && npm install && npm run build

It reads the local data/ JSON when run from this repo, or fetches the published dataset from GitHub when installed standalone — so it's always in sync. See mcp/README.md for setup.

How this data was collected

Each blueprint was sourced from the certifying body's official exam guide, certification page, or published PDF. The source_url field in every exam file links to the original source. No third-party question banks or proprietary content were used.

Data was collected and structured by QuizForge, a certification exam prep platform.
