HeyReach MCP server

What your assistant can do with it

• Read campaigns, their sequences and their stats
• Read LinkedIn conversations and the leads behind them
• Create lists and campaigns, and add leads
• Stop a lead in a campaign
• Manage blacklists and tags

How to connect it

1. Get the MCP key from your HeyReach account.
2. Add the HeyReach connector in Claude with that key.
3. Test with a call that reads a campaign, not just the tool list: the list loads with any key.

How we use it

Our LinkedIn outreach runs on HeyReach, and Claude drives it through this server: it reads campaign stats, pulls the conversations that need a human, stops leads who replied elsewhere and sets up new campaigns and lists. Two checks stay in the app: the daily invitation limit of each account and the final review of a sequence.

Where it breaks

• The tool list loads with any key, but every real call returns 401 without the right MCP key. A loaded tool list does not prove the key works.
• Adding leads straight into a draft campaign is refused. Add them to a list, then attach the list.
• Updating a sequence fails with a server error if an end step carries an empty payload.
• There is no way to delete a campaign.
• On 22/10/2026, updates to a lead's first name and company name were ignored; check them in the app after an edit.
• The daily invitation limit of an account and the review of a sequence are not available through it; both stay in the interface.

Our take. The right way to run HeyReach from Claude, and the server we rely on for LinkedIn. Test with a real call, and read back anything you edit.
