🔧 LinkedIn API Setup

Required OAuth Scopes

Your LinkedIn app needs these scopes (configured automatically):

  • openid - OpenID Connect authentication
  • profile - Basic profile access
  • email - Email address access

Application Configuration

  1. Application Type: Choose appropriate type for your use case
  2. Redirect URIs: http://localhost:44002/auth/linkedin/callback
  3. Scopes: Select openid, profile, email

🔒 Security & Privacy

  • Local-only storage - Tokens stored securely on your machine
  • OAuth 2.0 standard - Industry-standard authentication
  • No data transmission - No data sent to third parties
  • Automatic token refresh - Handles token expiration seamlessly
  • Secure token storage - Encrypted local storage

⚠️ Important Notes

Tool Limitations

  • 2/28 tools fully working (7.1%): get_my_profile, logout
  • 14/28 require LinkedIn Partner approval (50%): Advanced features need special permissions
  • 12/28 have API restrictions (42.9%): Limited by LinkedIn's standard API access

This is normal behavior for LinkedIn's API - most advanced features require special partnership approval.

Working Tools

✅ get_my_profile - Get your profile information
✅ logout - Clear authentication tokens

LinkedIn API Limitations

  • Most LinkedIn APIs require LinkedIn Partner Program approval
  • Standard developer accounts have very limited access
  • This affects job tools, messaging tools, content tools, etc.
  • Profile access works perfectly for standard accounts

Priority Order

Configuration values are resolved in this order:

  1. Command Line Arguments (highest priority)

    • --client-id overrides LINKEDIN_CLIENT_ID
    • --client-secret overrides LINKEDIN_CLIENT_SECRET
    • --default-user-id overrides LINKEDIN_USER_ID
    • --access-token overrides LINKEDIN_ACCESS_TOKEN

  2. Environment Variables (medium priority)

    • LINKEDIN_CLIENT_ID
    • LINKEDIN_CLIENT_SECRET
    • LINKEDIN_USER_ID
    • LINKEDIN_ACCESS_TOKEN

  3. Default Values (lowest priority)

    • Default user ID: default

Flexible Configuration Examples

Pure Environment Variables:

export LINKEDIN_CLIENT_ID="86yi0odon2lx3g"
export LINKEDIN_CLIENT_SECRET="WPL_AP1.your_secret"
linkedin-mcp-server --setup

Pure Command Line Arguments:

linkedin-mcp-server --client-id "86yi0odon2lx3g" --client-secret "WPL_AP1.your_secret" --setup

Mixed Configuration (arguments override environment):

export LINKEDIN_CLIENT_ID="old_id"
export LINKEDIN_CLIENT_SECRET="old_secret"
linkedin-mcp-server --client-id "new_id" --setup  # Uses new_id and old_secret

🆘 Troubleshooting

Common Issues

Authentication Failed

# Clear tokens and re-authenticate
linkedin-mcp-server --logout
linkedin-mcp-server --setup

Missing Credentials

  • Ensure LINKEDIN_CLIENT_ID and LINKEDIN_CLIENT_SECRET are set
  • Check SIYA Desktop configuration file

Tool Errors

  • Most tools require LinkedIn Partner approval (expected behavior)
  • Use get_my_profile to test basic functionality

Debug Mode

linkedin-mcp-server --debug
# Check logs at: /tmp/linkedin-mcp-server.log
