Quick Start

# Install from npm (recommended)
npx @eggisatriadev/linkedin-mcp

# Or install locally
npm install @eggisatriadev/linkedin-mcp

# Set your access token
export LINKEDIN_ACCESS_TOKEN=AQX_your_token_here

# Run the server
npx @eggisatriadev/linkedin-mcp

For Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "linkedin": {
      "command": "npx",
      "args": ["-y", "@eggisatriadev/linkedin-mcp"],
      "env": {
        "LINKEDIN_ACCESS_TOKEN": "AQX_your_token_here"
      }
    }
  }
}

For OpenCode

Add to your opencode.json:

{
  "mcpServers": {
    "linkedin": {
      "command": "npx",
      "args": ["-y", "@eggisatriadev/linkedin-mcp"],
      "env": {
        "LINKEDIN_ACCESS_TOKEN": "AQX_your_token_here"
      }
    }
  }
}

Setup

1. Create a LinkedIn Developer App

• Go to https://www.linkedin.com/developers/apps
• Create a new app
• Add products:
  • Sign In with LinkedIn using OpenID Connect (auto-approved)
  • Share on LinkedIn (for posting capabilities)
• Note your Client ID and Client Secret
• Add http://localhost:8080 as an OAuth redirect URL

2. Generate Access Token

The easiest way is to use the OAuth 2.0 token generator in the LinkedIn Developer Portal:

• Go to your app → Auth tab
• In OAuth 2.0 settings, find the access token section
• Select scopes: openid, profile, email, w_member_social
• Generate and copy the token

3. Run the Server

# Install dependencies
npm install

# Set your token
export LINKEDIN_ACCESS_TOKEN=AQX_your_token_here

# Build and run
npm run build
npm start

4. Connect to Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "linkedin": {
      "command": "node",
      "args": ["/absolute/path/to/linkedin-mcp-server/dist/index.js"],
      "env": {
        "LINKEDIN_ACCESS_TOKEN": "AQX_your_token_here"
      }
    }
  }
}

5. Connect to OpenCode

Add to your opencode.json (or use the MCP config):

{
  "mcpServers": {
    "linkedin": {
      "command": "node",
      "args": ["/absolute/path/to/linkedin-mcp-server/dist/index.js"],
      "env": {
        "LINKEDIN_ACCESS_TOKEN": "AQX_your_token_here"
      }
    }
  }
}

OAuth PKCE Login (No Token Required)

Skip step 2 — let the server handle authentication interactively:

# Required: set your LinkedIn app credentials
export LINKEDIN_CLIENT_ID=your_client_id
export LINKEDIN_CLIENT_SECRET=your_client_secret

# Run the server (it will detect no token and guide you)
npm run build
npm start

# Or from npm package:
npx @eggisatriadev/linkedin-mcp

Then call the linkedin_oauth_login tool from your MCP client:

• port (optional): Callback server port (default: 8080)
• open_browser (optional): Auto-open browser (default: true)
• timeout (optional): Max wait in ms (default: 120000)

The flow:

• Server starts a local HTTP server on port 8080
• Opens your browser to LinkedIn's authorization page
• You approve the request
• LinkedIn redirects to localhost — server captures the code
• Server exchanges the code for an access token via PKCE S256
• Token is saved to ~/.config/linkedin-mcp/config.json
• All tools immediately work without further setup

Media Upload

LinkedIn supports image upload via a 3-step /rest/images flow:

• Initialize: POST /rest/images?action=initializeUpload → returns uploadUrl + image URN
• Upload binary: PUT {uploadUrl} with image data
• Attach to post: Use the image URN as media.id in createPost()

Supported formats: JPEG, PNG, GIF (static) Max file size: 10 MB Recommended dimensions: 2048×2048px

Image upload happens automatically when you pass a media_url parameter to linkedin_create_post. The MediaUploader handles retries on expired upload URLs and validates format/size before uploading.

Development

# Watch mode (auto-reload)
npm run dev

# Build
npm run build

# Test with MCP Inspector
npm run inspector

Architecture

The server follows a layered architecture with four bounded contexts:

Token Resolution Chain

• LINKEDIN_ACCESS_TOKEN env var (highest priority)
• ~/.config/linkedin-mcp/config.json (persistent local token)
• OAuth PKCE flow (if LINKEDIN_CLIENT_ID + LINKEDIN_CLIENT_SECRET are set)

See tech-design.md for the full architecture, API contracts, data flow diagrams, and ADRs.
