Install the Reachmcp Chrome extension
Install the Reachmcp Chrome extension and sign in to your Reachmcp account. The extension connects to your LinkedIn session directly in your browser — no password is shared, and you can uninstall it at any time to revoke access.

Get your API key from the dashboard
Once your LinkedIn account is connected, go to Settings → API Key in your Reachmcp dashboard and copy your personal key. This key identifies your account and is passed as the X-API-Key header on every request.

Create a Header Auth credential in n8n
In n8n, go to Credentials → New → Header Auth and configure it as follows. This credential can be reused across all your Reachmcp nodes:
Name: Reachmcp Header name: X-API-Key Header value: YOUR_API_KEY

Pipe the exported profiles into a Google Sheets node, a CRM webhook, an AI node for personalization, or a second HTTP Request node to send messages — your workflow, your rules.
