### Description (declared)

# SeleniumBase MCP Servers

### This package provides three different [SeleniumBase](https://github.com/seleniumbase/SeleniumBase) MCP servers for driving stealthy browser automation over the [Model Context Protocol](https://modelcontextprotocol.io).

Here are the **three server variants** in this folder:

| File | Backs onto | Best for |
|---|---|---|
| `cdp_server.py` | `seleniumbase.sb_cdp.Chrome()` (Pure CDP Mode, sync) | Scraping/automation against bot-detection (Cloudflare, etc.) No WebDriver at all. Includes CAPTCHA-solving. |
| `driver_server.py` | `seleniumbase.Driver()` (WebDriver) | General automation with Selenium ecosystem support. |
| `sb_server.py` | `seleniumbase.SB()` (used without `with`, via manual `__enter__`/`__exit__`) | The broadest API surface: Everything `Driver` offers, plus drag-and-drop, MFA-handling, file downloads, etc. Can switch to CDP Mode mid-flow via `activate_cdp_mode` |

All three set `headless=False` by default, where the browser window is visible unless you pass `headless=True` when starting a session.

Point your MCP client config at whichever `*_server.py` fits the task (see step 3 below), or register all three under different names.

## 1. Install

(Requires Python 3.10+ and [uv](https://docs.astral.sh/uv/getting-started/installation/))

```bash
git clone https://github.com/seleniumbase/seleniumbase-mcp.git
cd seleniumbase-mcp
uv sync
```

`uv sync` reads `pyproject.toml`, creates a `.venv/` in this folder, and installs the `seleniumbase[mcp]` dependency along with this project itself, which registers three console-script commands via `[project.scripts]`:

- `seleniumbase-cdp`
- `seleniumbase-driver`
- `seleniumbase-sb`

Each just calls that server file's `main()` function (`mcp.run(transport="stdio")`). This is what lets `uv run <name>` work as the MCP client command in steps 3 and 4 below.

```bash
# SeleniumBase's Driver() and SB() formats need a browser driver downloaded:
uv run seleniumbase get chromedriver
# (Not need…
