## Quick Start
### Installation
#### Method 1: NPM Package (Recommended)
```bash
# Install globally (Playwright installs automatically)
npm install -g @ricardodeazambuja/browser-mcp-server
# Or use directly with npx (no installation needed)
npx @ricardodeazambuja/browser-mcp-server
```
**Note:** Playwright is installed automatically as a dependency. The server will automatically detect and use your system Chrome/Chromium if available, or fall back to Playwright's Chromium.
#### Method 2: Clone Repository (For Development)
```bash
# Clone the repository
git clone https://github.com/ricardodeazambuja/browser-mcp-server.git
cd browser-mcp-server
# Install dependencies (includes Playwright)
npm install
# Optional: Install Chromium browser if not using system Chrome
npx playwright install chromium
```
#### Method 3: Direct Download (Single File)
```bash
# Download the main file directly (no git required)
curl -o src/index.js \
https://raw.githubusercontent.com/ricardodeazambuja/browser-mcp-server/main/src/index.js
# Install Playwright
npm install playwright
# Optional: Install Chromium browser if not using system Chrome
npx playwright install chromium
```
### Usage with Claude Desktop
Add to your Claude Desktop config (`~/Library/Application Support/Claude/claude_desktop_config.json` on macOS):
**Using local installation:**
```json
{
"mcpServers": {
"browser-tools": {
"command": "node",
"args": ["/absolute/path/to/src/index.js"]
}
}
}
```
**Using NPM:**
```json
{
"mcpServers": {
"browser-tools": {
"command": "npx",
"args": ["-y", "@ricardodeazambuja/browser-mcp-server"]
}
}
}
```
**Note:** Replace `/absolute/path/to/` with the actual path where you installed the file.
### Usage with Antigravity
Add to `~/.gemini/antigravity/mcp_config.json`:
**Using local installation:**
```json
{
"mcpServers": {
"browser-tools": {
"command": "node",
"args": ["/home/username/.gemini/antigravity/src/index.js"]
}
}
}
```
**Using NPM:**
```json
{
"mcpServers": {
"browser-tools": {
"command": "npx",
"args": ["-y", "@ricardodeazambuja/browser-mcp-server"]
}
}
}
```
Then refresh MCP servers in Antigravity.
### Usage with Claude Code
Add the browser-mcp-server using the Claude CLI:
**Using local installation:**
```bash
# Install the MCP server with default isolated profile
claude mcp add --transport stdio browser \
-- node /absolute/path/to/src/index.js
# Or with custom browser profile for more control
claude mcp add --transport stdio browser \
--env MCP_BROWSER_PROFILE=/path/to/custom/profile \
-- node /absolute/path/to/src/index.js
```
**Using NPM:**
```bash
# Install using npx (no local installation needed)
claude mcp add --transport stdio browser \
-- npx -y @ricardodeazambuja/browser-mcp-server
# With custom browser profile
claude mcp add --transport stdio browser \
--env MCP_BROWSER_PROFILE=/path/to/custom/profile \
-- npx -y @ricardodeazambuja/browser-mcp-server
```
**Verify installation:**
```bash
# List all MCP servers
claude mcp list
# Check server status
claude mcp get browser
```
**Example usage in Claude Code:**
```bash
# Natural language commands
> Navigate to https://example.com and take a screenshot
> Click the login button and fill in the username field
> What's the text in the .main-content selector?
# Direct tool invocation via slash commands
> /mcp__browser__browser_navigate https://example.com
> /mcp__browser__browser_screenshot
```
**Note:** The server uses an isolated browser profile at `/tmp/chrome-mcp-profile` by default, ensuring it won't access your personal Chrome cookies or data.
### Usage with Gemini CLI
Add the browser-mcp-server using the Gemini CLI commands:
**Using local installation:**
```bash
# Install the MCP server with default isolated profile
gemini mcp add browser node /absolute/path/to/src/index.js
# Or with custom browser profile
gemini mcp add -e MCP_BROWSER_PROFILE=/path/to/custom/profile browser \
node /absolute/path/to/src/index.js
```
**Using NPM:**
```bash
# Install using npx (no local installation needed)
gemini mcp add browser npx -y @ricardodeazambuja/browser-mcp-server
# With custom browser profile
gemini mcp add -e MCP_BROWSER_PROFILE=/path/to/custom/profile browser \
npx -y @ricardodeazambuja/browser-mcp-server
```
**Management commands:**
```bash
# List all configured MCP servers
gemini mcp list
# Remove the server if needed
gemini mcp remove browser
```
**Example usage in Gemini CLI:**
```bash
# Natural language commands

### Getting Started with CDP Tools
```javascript
// Start CPU profiling
browser_perf_start_profile({})
// ... perform actions to profile ...
browser_perf_stop_profile({}) // Get results
// Monitor network activity
browser_net_start_monitoring({})
// ... navigate and interact ...
browser_net_get_requests({ filter: 'api' })
browser_net_export_har({})
// Security audit
browser_sec_get_security_headers({})
browser_sec_start_csp_monitoring({})
// ... trigger violations ...
browser_sec_get_csp_violations({})
// Inspect storage
browser_storage_get_indexeddb({ databaseName: 'myDB' })
browser_storage_get_cache_storage({ cacheName: 'my-cache-v1' })
```
**Note**: All CDP tools have comprehensive documentation available via `browser_docs({ toolName: 'browser_perf_start_profile' })`.
## On-Demand Documentation
The `browser_docs` tool provides comprehensive documentation for all browser tools **without increasing token overhead** in normal operations.
### Why This Matters
- **Token Efficient**: Tool descriptions stay concise (saving tokens on every request)
- **Comprehensive**: Detailed docs available when needed (return schemas, examples, caveats)
- **Self-Documenting**: AI agents can discover tool capabilities on-demand
### What You Get
When calling `browser_docs(toolName)`, you receive:
- **Parameter Details**: Types, optionality, defaults, enums
- **Return Value Schemas**: Exact structure of what the tool returns
- **Selector Syntax**: How to write Playwright selectors (CSS, text, data attributes)
- **Important Caveats**: Warnings about CORS, clearing behavior, state management
- **Practical Examples**: Real-world usage patterns
### Usage
```javascript
// Get docs for a specific tool
browser_docs({ toolName: 'browser_get_audio_analysis' })
// List all available tools
browser_docs({})
// Invalid tool name suggests similar tools
browser_docs({ toolName: 'navigate' })
// → Did you mean: browser_navigate, browser_go_back, ...
```
### Example Output
```
📖 browser_type(selector, text)
Type text into an input field.
Parameters:
• selector (string, required) - Playwright selector for the input
• text (string, required) - Text to type
Returns:
{ content: [{ type: 'text', text: 'Typed into <selector>' }] }
⚠️ Important:
• Uses page.fill() which CLEARS the field first, then types
• Does NOT append to existing text
Example:
browser_type({ selector: '#username', text: 'john@example.com' })
```
## Examples
### Navigate and Screenshot
```javascript
// Agent uses:
browser_navigate("https://example.com")
browser_screenshot(fullPage: true)
```
### Debug JavaScript Errors
```javascript
// Agent uses:
browser_console_start()
browser_navigate("https://myapp.com")
browser_click("#submit-button")
browser_console_get(filter: "error")
// Shows: ❌ [ERROR] Uncaught TypeError: ...
```
### Media Monitoring & Control
```javascript
// Agent uses:
browser_navigate("https://youtube.com/watch?v=...")
browser_get_media_summary() // See active video state
browser_control_media(selector: "video", action: "play")
browser_get_audio_analysis(durationMs: 2000) // "Hear" the volume
```
### Multi-Tab Automation
```javascript
// Agent uses:
browser_navigate("https://wikipedia.org")
browser_new_page("https://google.com")
browser_list_pages() // Shows 2 pages
browser_switch_page(0) // Back to Wikipedia
```
### Pixel-Based Interaction

```
## How It Works
### Three-Tier Browser Strategy (Automatic)
The server automatically chooses the best browser option:
**Tier 1 - Antigravity Mode:**
- Detects Chrome on port 9222
- Connects to existing Antigravity browser
- Uses Antigravity's browser profile
- No new browser window
**Tier 2 - System Chrome/Chromium:**
- Searches common locations: `/usr/bin/google-chrome`, `/usr/bin/chromium`, etc.
- Uses system-installed Chrome if found
- Saves ~275MB (no Chromium download needed)
- Uses isolated profile (`/tmp/chrome-mcp-profile`)
**Tier 3 - Playwright Chromium:**
- Falls back to Playwright's bundled Chromium
- Requires: `npx playwright install chromium`
- Uses isolated profile (`/tmp/chrome-mcp-profile`)
- New browser window appears
### Safety Features
- **Isolated Profile**: Uses `/tmp/chrome-mcp-profile` (not your personal Chrome!)
- **No Setup Dialogs**: Silent startup with `--no-first-run` flags
- **Clean Environment**: No extensions, sync, or background updates
- **Reproducible**: Same behavior across systems
## Security
This MCP server provides powerful browser automation capabilities. Please review these security considerations:
### Isolated Browser Profile
- Uses `/tmp/chrome-mcp-profile` by default (configurable via `MCP_BROWSER_PROFILE`)
- **Does NOT access your personal Chrome data** (cookies, passwords, history)
- Each instance runs in a clean, isolated environment
### Tool Safety
**browser_evaluate**: Executes arbitrary JavaScript in the browser context
- Code runs in browser sandbox (no access to your host system)
- Only executes when explicitly called by MCP client
- Requires user approval in most MCP clients
- **Recommendation**: Only use with trusted MCP clients and review code when possible
**browser_navigate**: Navigates to any URL
- Can visit any website the browser can access
- Uses isolated profile to prevent cookie/session theft
- **Recommendation**: Be cautious with URLs from untrusted sources
### Debug Logs
- Server logs to `/tmp/mcp-browser-server.log`
- Logs may contain visited URLs and error messages
- Log file is cleared on system reboot (stored in `/tmp`)
- **Does NOT log** page content or sensitive data
### Best Practices
- ✅ Only use with trusted MCP clients (Claude Desktop, Antigravity, etc.)
- ✅ Review automation scripts before execution when possible
- ✅ Use the default isolated profile (don't point to your personal Chrome)
- ✅ Report security issues via [GitHub Issues](https://github.com/ricardodeazambuja/browser-mcp-server/issues)
## Configuration
### Environment Variables
```bash
# Custom browser profile location (optional)
export MCP_BROWSER_PROFILE="$HOME/.mcp-browser-profile"
# Then run the server
node src/index.js
```
### MCP Config with Environment Variables
```json
{
"mcpServers": {
"browser-tools": {
"command": "node",
"args": ["/path/to/src/index.js"],
"env": {
"MCP_BROWSER_PROFILE": "/tmp/my-custom-profile"
}
}
}
}
```
## Troubleshooting
### "No Chrome/Chromium browser found"
The server provides helpful error messages with multiple solutions:
**Option 1 - Install system Chrome/Chromium (Recommended):**
```bash
# Ubuntu/Debian
sudo apt install google-chrome-stable
# or
sudo apt install chromium-browser
# Fedora
sudo dnf install google-chrome-stable
# macOS
brew install --cask google-chrome
```
**Option 2 - Install Playwright's Chromium:**
```bash
npm install playwright
npx playwright install chromium
```
**Option 3 - Use with Antigravity:**
- Click the Chrome logo (top right) to launch browser
- The MCP server will automatically connect
### Check Server Status
Use the `browser_health_check` tool to verify:
- Which mode is active (Antigravity / System Chrome / Playwright Chromium)
- Playwright source
- Browser profile location
- Current page URL
### Check Server Status
Use the `browser_health_check` tool to verify:
- Connection mode (Antigravity vs Standalone)
- Playwright source
- Browser profile location
- Current page URL

Scored across 63 tools
Most tools have distinct purposes with clear boundaries, such as browser_click for clicking elements and browser_navigate for URL navigation. However, some overlap exists, like browser_click and browser_mouse_click, which could cause confusion despite different use cases (selector-based vs. coordinate-based). The descriptions help differentiate them, but the overlap is noticeable.
All tool names follow a consistent snake_case pattern with a 'browser_' prefix and descriptive verb_noun combinations, such as browser_get_dom and browser_start_video_recording. This uniformity makes the tool set predictable and easy to navigate, with no deviations in naming style.
With 63 tools, the count is excessive for a browser automation server, making it overwhelming and likely to cause analysis paralysis for agents. While the domain is broad, a more focused set of 15-25 tools would be more manageable and appropriate for typical use cases.
The tool set provides comprehensive coverage for browser automation, including navigation, interaction, performance monitoring, security analysis, and media control. It supports full CRUD-like operations for web elements, network requests, and storage, with no obvious gaps that would hinder agent workflows.
