Use VieNeu in Claude Code

Add the server

claude mcp add --transport http vieneu https://api.vieneu.io/mcp

Then, inside Claude Code, run /mcp, pick vieneu and choose Authenticate. Your browser opens the VieNeu consent page. It shows a yellow note that the app runs on your computer (the callback is 127.0.0.1 or localhost) — that is expected for Claude Code. Press Cho phép (Allow).

From a shell you can also start the sign-in with:

claude mcp login vieneu

Where it is saved (--scope)

Scope	Stored in	Use when
local (default)	~/.claude.json, this project only	Just you, just here
user	~/.claude.json, every project	You want VieNeu everywhere
project	.mcp.json in the repository	The whole team should get it (each person still signs in)

claude mcp add --transport http --scope user vieneu https://api.vieneu.io/mcp

Using an API key instead

For CI or machines where a browser sign-in is not possible:

claude mcp add --transport http vieneu https://api.vieneu.io/mcp \
  --header "X-API-Key: vn_sk_..."

In a shared .mcp.json, reference an environment variable instead of the key:

{
  "mcpServers": {
    "vieneu": {
      "type": "http",
      "url": "https://api.vieneu.io/mcp",
      "headers": { "X-API-Key": "${VIENEU_API_KEY}" }
    }
  }
}

Use it

Ask in the session, for example: "Đọc README tiếng Việt này bằng giọng nữ miền Nam và cho mình link tải." Claude Code shows the reply and the download link; it has no inline player.

Remove it

claude mcp remove vieneu

and, if you signed in, Developer → Gỡ kết nối on vieneu.io.
