Browserbash MCP Server

Plain-English browser automation. No selectors. Free and open-source. You write a plain-English objective. An AI agent drives a real Chrome browser step by step - no selectors, no scripts. Ollama-first, so it runs on free local models with no API keys and nothing ever leaves your machine.

People who work with Anthropic and Browserbase and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Browserbash

before you install - you'll need

Set ANTHROPIC_API_KEY, BROWSERBASE_API_KEY, LT_USERNAME before connecting.

Claude Code

claude mcp add pramoddutta-browserbash -- npx -y browserbash-cli

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "pramoddutta-browserbash": {
      "command": "npx",
      "args": [
        "-y",
        "browserbash-cli"
      ]
    }
  }
}

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

Using another client? Same JSON, different key

license no standard license detected - usage rights unclear; check the repo before commercial use

npm package browserbash-cli - unscoped; check the name against the project README before installing

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