Installation

npx camoufox-mcp

Claude Desktop Configuration

Add to claude_desktop_config.json:

Basic: ``json { "mcpServers": { "camoufox": { "command": "npx", "args": ["camoufox-mcp"] } } } ``

With Proxy (via env vars): ``json { "mcpServers": { "camoufox": { "command": "npx", "args": ["camoufox-mcp"], "env": { "PROXY_SERVER": "http://1.2.3.4:8080", "PROXY_USER": "username", "PROXY_PASS": "password" } } } } ``

Then in ~/.config/camoufox-mcp/settings.json: ``json { "proxy": { "enabled": true, "server": "${PROXY_SERVER}", "username": "${PROXY_USER}", "password": "${PROXY_PASS}", "geoip": true } } ``

Tools

Session Management

Sessions provide isolated browser contexts — each session has its own cookies, localStorage, and cache. Use sessions to run multiple authenticated profiles simultaneously.

| Tool | Description | |------|-------------| | create_session | Create a new isolated session, optionally pre-loading cookies/localStorage from a JSON file | | list_sessions | List all sessions with their page counts and metadata | | save_session | Export a session's cookies and localStorage to a JSON file | | close_session | Close a session and all its pages | | list_context_files | List available context files registered in settings |

Page Management

| Tool | Description | |------|-------------| | new_page | Create a new page, optionally in a specific session | | list_pages | List all open pages with their session IDs | | select_page | Set a page as active | | close_page | Close a page |

Navigation & Interaction

| Tool | Description | |------|-------------| | navigate_page | Navigate to URL, back, forward, or reload | | click | Click an element by UID | | hover | Hover over an element | | fill | Fill a form field | | fill_form | Fill multiple form fields at once | | press_key | Press a key or key combination | | drag | Drag an element to another |

Inspection

| Tool | Description | |------|-------------| | take_snapshot | Text snapshot with interactive element UIDs | | take_screenshot | Screenshot of page or element | | get_page_text | Extract text content | | evaluate_mainworld | Run JS in page context (sync only) | | evaluate_isolated | Run JS in isolated context (async OK) | | get_framework_state | Extract Next.js/Nuxt.js state |

Context Injection

| Tool | Description | |------|-------------| | inject_context | Inject cookies + localStorage from a JSON file into a session |

Monitoring

| Tool | Description | |------|-------------| | start_network_capture / stop_network_capture | Capture network requests | | get_network_logs / clear_network_logs | View/clear captured requests | | intercept_network / remove_intercept | Block or modify requests | | start_console_capture / stop_console_capture | Capture console messages | | get_console_logs / clear_console_logs | View/clear console messages | | start_recording / stop_recording / get_recording_status | Record user interactions |

Utility

| Tool | Description | |------|-------------| | dismiss_popups | Auto-dismiss cookie consent popups | | wait_for | Wait for text or selector | | wait_for_navigation | Wait for navigation to complete | | reload_settings | Reload settings from config | | get_config_paths | Show config file paths | | init_user_config | Initialize user config directory |

Sessions

Sessions enable running multiple authenticated profiles in parallel. Each session is an isolated browser context with its own cookies and localStorage.

Browser (single Camoufox instance)
  ├── Session "github" (cookies from github.json)
  │     ├── Page: github.com
  │     └── Page: github.com/repo
  ├── Session "linkedin" (cookies from linkedin.json)
  │     └── Page: linkedin.com/feed
  └── Session "default" (no pre-loaded state)
        └── Page: example.com

Usage Examples

Create a session with pre-loaded authentication:

create_session with contextPath: "github-cookies.json" — returns a sessionId
new_page with url: "https://github.com" and the sessionId — opens GitHub already logged in

Run two accounts simultaneously:

create_session with contextPath: "account1.json" — session A
create_session with contextPath: "account2.json" — session B
new_page in session A — logged in as account 1
new_page in session B — logged in as account 2

Save session state for later:

Log in manually in a session
save_session with outputPath: "my-session.json" — exports cookies + localStorage
Next time, create_session with contextPath: "my-session.json" — restored

Context File Format

Context files use Playwright's storageState format:

{
  "cookies": [
    {
      "name": "session_id",
      "value": "abc123",
      "domain": ".example.com",
      "path": "/",
      "expires": 1735689600,
      "httpOnly": true,
      "secure": true,
      "sameSite": "Lax"
    }
  ],
  "origins": [
    {
      "origin": "https://example.com",
      "localStorage": [
        { "name": "token", "value": "xyz789" }
      ]
    }
  ]
}

Registering Context Files in Settings

Add context file paths to settings.json to make them discoverable via list_context_files. Sessions are created lazily on demand — no memory is used until the agent calls create_session:

{
  "contextPaths": [
    "/path/to/github-cookies.json",
    "/path/to/linkedin-cookies.json"
  ]
}

The agent can then call list_context_files to see what's available, and create_session with the desired contextPath to load it when needed.

Settings

Create ~/.config/camoufox-mcp/settings.json:

{
  "browser": {
    "headless": false,
    "viewport": [1280, 1080],
    "timeout": 30000,
    "humanize": 0.5
  },
  "proxy": {
    "enabled": true,
    "server": "http://proxy.example.com:8080",
    "username": "user",
    "password": "pass",
    "geoip": true
  },
  "contextPaths": []
}

Proxy Examples

HTTP/HTTPS Proxy: ``json { "proxy": { "enabled": true, "server": "http://1.2.3.4:8080" } } ``

SOCKS5 Proxy: ``json { "proxy": { "enabled": true, "server": "socks5://1.2.3.4:1080" } } ``

With Authentication (using env vars): ``json { "proxy": { "enabled": true, "server": "${PROXY_SERVER}", "username": "${PROXY_USER}", "password": "${PROXY_PASS}", "geoip": true } } ``

geoip: true auto-adjusts browser timezone/locale based on proxy IP location.
