01 · Install Server Browser

Claude Code

claude mcp add bytedance-ui-tars-desktop-packages-agent -- npx -y @agent-infra/mcp-server-browser

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "bytedance-ui-tars-desktop-packages-agent": {
      "command": "npx",
      "args": [
        "-y",
        "@agent-infra/mcp-server-browser"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license Apache-2.0 - declared in the repository

npm package @agent-infra/mcp-server-browser - the @agent-infra scope differs from the repo owner (bytedance); confirm it's the project's official package

registry namespace io.github.bytedance is GitHub-verified and matches the repo owner
