NAVER MYBOX MCP server

naver-mybox-mcp

<!-- mcp-name: io.github.java-jaydev/naver-mybox-mcp -->

An MCP server for NAVER MYBOX (네이버 마이박스) — list, search, download and upload files in your MYBOX cloud drive from any MCP client (Claude Code, Claude Desktop, and others).

MYBOX opened a public API in August 2026 (developers.mybox.naver.com). This wraps it as tools. Unofficial, not affiliated with NAVER.

Why

Phone photos land in MYBOX automatically. Getting them onto a machine meant clicking through the web UI. With this, an agent can fetch "every photo taken on 10–11 September" into a working folder in one step.

Install

Requires Python 3.10+.

pip install naver-mybox-mcp

Get a token

Authentication is a personal access token, not OAuth.

1. Sign in at MYBOX on the web.
2. Settings → account and personal access token management → create token.
3. Copy it immediately — it is shown once.

Up to five tokens per account; each lasts 30, 60, 90 or 180 days, and MYBOX emails you 7 days and 1 day before expiry. Anyone holding the token can reach the whole drive, so treat it as a password and never commit it.

Provide it as the MYBOX_PAT environment variable, or put it on one line in ~/.mybox/token.

Configure your MCP client

{
  "mcpServers": {
    "mybox": {
      "command": "naver-mybox-mcp",
      "env": { "MYBOX_PAT": "mbx_pat_..." }
    }
  }
}

In Claude Code: claude mcp add mybox --env MYBOXPAT=mbxpat_... -- naver-mybox-mcp

Tools

Deliberately missing: delete

The API can delete files, empty the trash and set its auto-delete period. Those tools are not exposed here. An agent that can read and write files is useful; one that can destroy them is a different risk, and the web UI is right there. Open an issue if you need them behind a flag.

Quotas

The docs publish per-plan limits and warn that bursts or abuse may be blocked without prior notice, so the client paces itself below the lowest documented per-minute limits (9/min for search, 55/min otherwise). Free accounts can use the API; the plan only changes the limits.

Download limits are daily and the client cannot pace around them. Search first, count the results, and fetch in batches if the set is large.

Notes on the API

go there as multipart field Filedata.

• Base URL https://open-api.mybox.naver.com/v1
• Upload is two steps: POST /drive/files returns an uploadUrl (48h, single use); the bytes

(10 minutes, single use).

• Download is two steps: GET /drive/files/{id}/download returns a downloadUrl

only in the web and mobile apps. An empty listing does not mean an empty drive.

• Paging: responseMetaData.nextCursor goes back as cursor.
• Search needs at least one of keyword, category or a date bound.
• Encrypted folders and folders shared with you are not exposed by the API — they exist
