Getting Started

Maintainer disclosure: this first-party listing is submitted on behalf of the Protostatis/Unchained project. Requires Python 3.10+. Install with `pipx install pyunbrowser`, then configure the MCP client with command `unbrowser` and args `["--mcp"]`. For discovery and public-page smoke tests only, the shared Streamable HTTP endpoint is `https://unchainedsky.com/unbrowser-mcp`. Do not send secrets, private cookies, or authenticated browsing tasks to the shared endpoint; use the local install for those workflows.

Example
{
  "mcpServers": {
    "unbrowser": {
      "command": "unbrowser",
      "args": ["--mcp"]
    }
