LinkedIn Sales & Navigator MCP Server

LinkedIn Sales & Navigator MCP Server

A Model Context Protocol (MCP) server that connects AI assistants to LinkedIn and LinkedIn Sales Navigator using cookie-based authentication. Provides 17 tools for viewing profiles, searching people & companies, messaging, managing connections, and full Sales Navigator access — all through LinkedIn's internal Voyager API.

Built with TypeScript, @modelcontextprotocol/sdk, Zod, undici, and Puppeteer with stealth plugin.

Features

• 17 tools — Profiles, search, companies, messaging, connections, and full Sales Navigator
• Cookie-based auth — No LinkedIn Developer account or OAuth app required
• Dual-engine architecture — Fast HTTP (undici) for reads, headless Puppeteer with stealth plugin for messaging & Sales Navigator
• Anti-bot bypass — Puppeteer-extra with StealthPlugin bypasses LinkedIn's automation detection
• Clean responses — Deeply nested LinkedIn Voyager API responses are parsed into readable JSON
• Type-safe — Written in strict TypeScript with Zod schema validation on all tool inputs
• MCP standard — Works with any MCP-compatible client (Claude Desktop, Claude Code, etc.)

Prerequisites

• Node.js >= 18.0.0
• npm >= 8.0.0
• A LinkedIn account with an active session in your browser
• A Sales Navigator subscription (for Sales Navigator tools only)

Getting Your LinkedIn Cookie

The server authenticates using the li_at cookie from your logged-in LinkedIn session:

1. Open linkedin.com in your browser and log in
2. Open Developer Tools (F12 or Ctrl+Shift+I)
3. Go to the Application tab (Chrome/Edge) or Storage tab (Firefox)
4. In the left sidebar, expand Cookies and click on https://www.linkedin.com
5. Find and copy the li_at cookie value

Important: The li_at cookie expires periodically. If you get authentication errors, extract a fresh cookie from your browser.
