# selenium-mcp
Selenium MCP server for AI agents — **39 tools** for real-browser automation: navigation, clicking, typing, assertions, screenshots, multi-session management, page snapshots with stable element refs, persistent selector hints, and batched multi-step execution.

[](package.json)
Built with TypeScript, the official MCP SDK, and Selenium WebDriver — strict zod input validation, explicit waits, and structured responses designed for LLM agents.

## Setup

<summary><strong>Claude Code</strong></summary>
```bash
claude mcp add selenium -- npx -y @gaforov/selenium-mcp@latest
```
</details>
<details>
<summary><strong>Claude Desktop / Cursor / Windsurf / other MCP clients</strong></summary>
Add to your client's MCP config (e.g. `claude_desktop_config.json` or `.cursor/mcp.json`):
```json
{
"mcpServers": {
"selenium": {
"command": "npx",
"args": ["-y", "@gaforov/selenium-mcp@latest"]
}
}
}
```
</details>
<details>
<summary><strong>VS Code</strong></summary>
```bash
code --add-mcp '{"name":"selenium","command":"npx","args":["-y","@gaforov/selenium-mcp@latest"]}'
```
</details>
<details>
<summary><strong>Goose</strong></summary>
```bash
goose session --with-extension "npx -y @gaforov/selenium-mcp@latest"
```
</details>

<summary><strong>IntelliJ IDEA / JetBrains IDEs</strong></summary>
Settings → Tools → AI Assistant → Model Context Protocol → Add, with command `npx` and arguments `-y @gaforov/selenium-mcp@latest`. Full walkthrough in [docs/CLIENT_INTEGRATION.md](docs/CLIENT_INTEGRATION.md).
</details>
<details>
<summary><strong>From source</strong></summary>
```bash
git clone https://github.com/gaforov/selenium-mcp.git
cd selenium-mcp
npm install
npm run build
```
Then point your MCP client at `node /absolute/path/to/selenium-mcp/dist/server.js`.

## Example Usage
Ask your AI agent:
> Use selenium-mcp to open Chrome, go to https://example.com, read the page title, take a screenshot, and close the browser.
The agent chains `start_browser` → `navigate` → `get_title` → `take_screenshot` → `stop_browser` on its own — no scripting needed.
## Requirements
- Node.js 20+
- Chrome, Firefox, or Edge installed (Selenium Manager provisions the matching driver automatically)
## How it compares
Most Selenium MCP servers wrap WebDriver's basic commands. This one adds the layer that makes agents *reliable*:
| Capability | selenium-mcp | Typical Selenium MCP servers |
|---|:---:|:---:|
| Page snapshot with stable element refs (`capture_page`) | ✅ | rare |
| Persistent per-domain selector memory (`selector_hint_*`) | ✅ | ❌ |
| Parallel multi-session browsing | ✅ | rare |
| Batched multi-step execution in one call | ✅ | ❌ |
| Built-in test assertions | ✅ | some |
| Tool-call tracing (NDJSON audit log) | ✅ | ❌ |
| Strict input validation + structured errors | ✅ | varies |
## Why selenium-mcp
- **Snapshot-first workflows** — `capture_page` returns a page snapshot with stable element refs the agent can act on directly, no brittle selector guessing
- **Selector hints** — persist working locators per domain so repeat automations get faster and more reliable over time
- **Batched execution** — `batch_execute` runs constrained multi-step sequences in a single tool call, cutting round-trips
- **Multi-session** — create, select, list, and destroy parallel browser sessions
- **Agent-friendly errors** — every response is structured and validated with zod, so agents can recover instead of stalling
- **Optional tracing** — NDJSON trace of every tool call for debugging and auditing
## Tools (39)
| Category | Tools |
|---|---|
| Browser lifecycle | `start_browser`, `stop_browser`, `session_create`, `session_select`, `session_list`, `session_destroy` |
| Navigation | `open_url`, `navigate`, `get_current_url`, `get_title` |
| Element discovery | `find_element`, `wait_for_element`, `wait_until_visible`, `capture_page`, `get_page_source` |

| Reading | `get_text`, `get_attribute` |
| Assertions | `assert_text`, `assert_visible`, `assert_attribute` |
| Scripting | `execute_script`, `batch_execute` |
| Selector hints | `selector_hint_save`, `selector_hint_get`, `selector_hint_list`, `selector_hint_delete` |

## MCP Resources
- `browser-status://current` — live browser/session status
- `accessibility://current` — accessibility snapshot of the current page
## Optional Tracing
Enable lightweight NDJSON tracing of all tool calls:
```bash
SELENIUM_MCP_TRACE=true
SELENIUM_MCP_TRACE_PATH=./logs/selenium-mcp-trace.ndjson
```
If `SELENIUM_MCP_TRACE_PATH` is omitted, the default is `logs/selenium-mcp-trace.ndjson`.
