Gives Claude read access to your WaniKani spaced repetition data through six tools that pull profile info, lesson and review summaries, assignments, subjects (radicals, kanji, vocabulary), review statistics, and level progressions. You'll need a WaniKani API token to authenticate. This is useful when you want an AI to understand where you are in your Japanese kanji learning journey, analyze your review patterns, or help you strategize around upcoming lessons and reviews. It's read-only, so Claude can see your progress but can't modify anything. Part of a larger collection of Go-based MCP servers from the same author that includes similar Japanese learning integrations like Bunpro.
