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
Go to Settings → API Key in your Reachmcp dashboard and copy your personal key. It is passed as the X-API-Key header on every request. Keep it secret and rotate it if compromised.

Or use the MCP server for AI tool integration
If you're connecting to an AI assistant (Claude, ChatGPT…), use the MCP server instead — authentication is handled via OAuth directly from the AI interface, no API key needed:
MCP Server: https://app.reachmcp.com/mcp Auth: sign in via the AI connector interface Compatible with: Claude Desktop, ChatGPT Connectors, any MCP-compatible client.
