Run this in your terminal

claude mcp add kani --env WANIKANI_API_TOKEN=your-value --env WANIKANI_API_BASE_URL=your-value -- npx -y kani-mcp-server

Fill in the empty values before running it.

Common questions

Is Kani MCP Server safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: WANIKANI_API_TOKEN

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.4) reached the registry 16 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Kani MCP Server

A small, read-only Model Context Protocol server that gives MCP clients access to a user's WaniKani progress and WaniKani reference data through the official API v2.

It can answer questions such as:

What reviews and lessons are coming up today?
Which kanji are assigned at a given level?
Which subjects have the lowest review accuracy?
What notes or synonyms have I saved?

The server runs locally over stdio. It does not store data, expose an HTTP service, or modify WaniKani.

Requirements

Node.js 18 or newer
A WaniKani personal access token with read-only permissions, created in WaniKani API Tokens

Keep the token secret. It grants access to account and study data.

Install

The simplest MCP configuration runs the published package directly with npx:

"mcpServers": { "wanikani": { "command": "npx", "args": ["-y", "kani-mcp-server@latest"], "env": { "WANIKANI_API_TOKEN": "your-read-only-token" } } } }

Alternatively, install the executable globally:

npm install --global kani-mcp-server

kani-mcp-server

Restart the MCP client after changing its configuration. Prefer the client's secure secret facility, when available, over writing a token into a JSON file.

Run from source

git clone https://github.com/Alexxanddr/kani-mcp-server.git

cd kani-mcp-server npm ci cp .env.example .env

Edit .env and set WANIKANI_API_TOKEN.

npm run build node --env-file=.env dist/index.js

To configure an MCP client against a source checkout, replace the path and token:

"mcpServers": { "wanikani": { "command": "node", "args": ["/absolute/path/to/kani-mcp-server/dist/index.js"], "env": { "WANIKANI_API_TOKEN": "your-read-only-token" } } } }

The process communicates via MCP on stdin/stdout, so an empty terminal after startup is normal.

Tools

Tool	Purpose
`get_user`	User profile, level, preferences, and subscription state
`get_summary`	Lessons and reviews available during the next 24 hours
`list_assignments`	Assignments filtered by subjects, levels, SRS stages, or state
`list_subjects`	Radicals, kanji, vocabulary, and kana vocabulary
`list_review_statistics`	Accuracy and incorrect-answer totals by subject
`list_reviews`	Completed review history
`list_study_materials`	Personal notes and meaning/reading synonyms
`list_level_progressions`	Level progression history
`list_resets`	Account reset history
`list_spaced_repetition_systems`	SRS stage definitions
`list_voice_actors`	Pronunciation voice actor metadata
`get_resource`	One supported resource by type and numeric ID

Collection tools return one API page. Use page_after_id or page_before_id from the WaniKani collection pagination data to continue. Arrays are sent as the comma-delimited filters expected by the API.

Example prompts:

Show my WaniKani level and the reviews due in the next 24 hours.

List my level 10 kanji assignments and explain their current SRS stages. Find review statistics below 70%, then fetch the matching subjects.

See MCP contracts for exact inputs and outputs.

Configuration

Variable	Required	Meaning
`WANIKANI_API_TOKEN`	Yes	Personal WaniKani API v2 bearer token
`WANIKANI_API_BASE_URL`	No	API root; defaults to `https://api.wanikani.com/v2`

Changing the base URL sends the bearer token to that host. Remote overrides must use HTTPS; localhost HTTP is accepted for tests and local development.

Development

npm ci

npm run check npm pack --dry-run

npm run dev: run TypeScript directly over stdio
npm test: run unit and MCP contract tests
npm run type-check: check TypeScript without emitting files
npm run build: create the bundled executable in dist/

Read CONTRIBUTING.md, architecture, and testing before changing public tools.

Troubleshooting

`WANIKANI_API_TOKEN is required`: pass the variable in the MCP client's env block or start Node with --env-file=.env.
401 Unauthorized: verify the token and recreate it if it may have been exposed.
429 Too Many Requests: wait for WaniKani's rate-limit reset and request narrower collections.
Large responses: add filters and paginate rather than requesting broad subject or review histories.
Client shows disconnected: use an absolute script path, run npm run build, and confirm Node 18+ is on the client's PATH.

Limitations

Read-only: starting assignments, submitting reviews, changing user settings, and editing study materials are intentionally absent.
No automatic multi-page aggregation, caching, resources, or prompts.
API response objects are passed through unchanged, so upstream additions appear without a package release.
