Vessel Browser MCP Server

Vessel is a simple, clean web browser with an AI assistant built in. Browse the web normally, then ask Vessel to help research, navigate pages, summarize what you are reading, fill forms, or keep track of longer tasks. It runs locally over stdio via the published package.

People connecting browser automation tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Vessel Browser

before you install - you'll need

ELECTRON_MIRROR

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add unmodeled-tyler-vessel-browser -- npx -y @quanta-intellect/vessel-browser

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "unmodeled-tyler-vessel-browser": {
      "command": "npx",
      "args": [
        "-y",
        "@quanta-intellect/vessel-browser"
      ]
    }
  }
}

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

Using another client? Same JSON, different key

npm package @quanta-intellect/vessel-browser - the @quanta-intellect scope differs from the repo owner (unmodeled-tyler); confirm it's the project's official package

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