Use the Reachmcp REST API

Control LinkedIn programmatically from any language or tool. One API key, all LinkedIn actions — exports, messages, connections, scheduling and more.

🔐

Chrome extension required

Reachmcp works via a Chrome extension that connects to your LinkedIn session directly in your browser. No password is ever shared — the extension reads your LinkedIn session cookie securely. You can uninstall it at any time to revoke access.

1

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.
2

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.
3

Make your first request

All requests go to https://app.reachmcp.com/api. Pass your API key as an X-API-Key header on every call:
# 1. Get your account_id
curl https://app.reachmcp.com/api/linkedin-accounts \
  -H "X-API-Key: YOUR_API_KEY"

# 2. Scrape profiles from a LinkedIn search URL
curl "https://app.reachmcp.com/api/linkedin/ACCOUNT_ID/scrape-search?url=https%3A%2F%2Fwww.linkedin.com%2Fsearch%2Fresults%2Fpeople%2F%3Fkeywords%3Dcto%2Bparis&count=25" \
  -H "X-API-Key: YOUR_API_KEY"

# 3. Send a message
curl -X POST https://app.reachmcp.com/api/linkedin/ACCOUNT_ID/messages \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text": "Hi!", "recipient_linkedin_id": "https://linkedin.com/in/..."}'

Browse all available endpoints

The full API reference is available at app.reachmcp.com/scalar. It covers all LinkedIn actions: exports, messaging, connection management, post scheduling, activity, and more. Each endpoint is documented with request/response examples you can run directly in the browser.

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.
