LinkedIn Sales Navigator

CI npm version

MCP server for LinkedIn Sales Navigator — Browser automation via Playwright.

LinkedIn Sales Navigator doesn't provide a public API. This MCP server uses browser automation (Playwright) to control Sales Navigator through an authenticated browser session. It enables AI assistants to search leads, view profiles, manage lists, send InMails, and export data — all through the standard Model Context Protocol.

⚠️ Important Disclaimers

• This tool requires an active LinkedIn Sales Navigator subscription
• Browser automation: This operates by controlling a real browser — no API hacking
• Session required: You must be logged into LinkedIn in the browser instance
• Rate limiting: Use responsibly. LinkedIn may restrict accounts that perform excessive automation
• Terms of Service: Review LinkedIn's ToS before using automation tools
• No credentials stored: This tool never stores or handles LinkedIn passwords

Quick Start

Prerequisites

• Node.js ≥ 20
• LinkedIn Sales Navigator subscription with active session
• A browser with an active LinkedIn login (Chrome recommended)

Install

npm install globodai-mcp-linkedin-sales-navigator

Or clone and build from source:

git clone https://github.com/globodai-group/mcp-linkedin-sales-navigator.git
cd mcp-linkedin-sales-navigator
npm install
npm run build

Configuration

The server is configured via environment variables:

Variable	Default	Description
LSN_AUTH_METHOD	cdp	Authentication method: cdp, session, or cookies
LSN_CDP_ENDPOINT	http://localhost:9222	Chrome DevTools Protocol endpoint
LSN_USER_DATA_DIR	—	Path to Chrome user data directory (for session method)
LSN_COOKIES_PATH	—	Path to cookies JSON file (for cookies method)
LSN_HEADLESS	false	Run browser in headless mode
LSN_VIEWPORT_WIDTH	1280	Browser viewport width
LSN_VIEWPORT_HEIGHT	900	Browser viewport height
LSN_NAVIGATION_TIMEOUT	30000	Navigation timeout in ms
LSN_ACTION_TIMEOUT	10000	Action timeout in ms

Authentication Methods

1. CDP (Chrome DevTools Protocol) — Recommended

Connect to an already-running Chrome browser with an active LinkedIn session.

Start Chrome with remote debugging:

# macOS
/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome \
  --remote-debugging-port=9222

# Linux
google-chrome --remote-debugging-port=9222

# Windows
chrome.exe --remote-debugging-port=9222

Then log into LinkedIn Sales Navigator manually. The MCP server connects to this browser.

LSN_AUTH_METHOD=cdp LSN_CDP_ENDPOINT=http://localhost:9222 npx globodai-mcp-linkedin-sales-navigator

2. User Data Directory

Use an existing Chrome profile that's already logged into LinkedIn:

LSN_AUTH_METHOD=session LSN_USER_DATA_DIR=/path/to/chrome/profile npx globodai-mcp-linkedin-sales-navigator

3. Cookie-Based

Export your LinkedIn cookies and provide them as a JSON file:

LSN_AUTH_METHOD=cookies LSN_COOKIES_PATH=/path/to/linkedin-cookies.json npx globodai-mcp-linkedin-sales-navigator

Clawdbot / CORTX Integration

This MCP server is designed to work seamlessly with Clawdbot browser relay:

{
  "mcpServers": {
    "linkedin-sales-navigator": {
      "command": "npx",
      "args": ["globodai-mcp-linkedin-sales-navigator"],
      "env": {
        "LSN_AUTH_METHOD": "cdp",
        "LSN_CDP_ENDPOINT": "http://localhost:9222"
      }
    }
  }
}

When using Clawdbot's browser relay, the AI assistant can directly control a browser tab where you're logged into Sales Navigator — no additional setup needed.
