Why this matters
ChatGPT Desktop now supports MCP servers via the official connector flow. Configure once, use forever — the assistant gains every ReachOut capability through standard tool calls.
What you get
- Standard MCP transport — works with the same API key as Claude Desktop and Cursor.
- No custom GPT or Action setup required.
- Per-organization auth without exposing tenant IDs to the agent.
- Audit-log integration: every ChatGPT-driven action is replayable in Studio.
Setup in 4 steps
- Generate a ReachOut API key. Studio → Settings → API keys → Create.
- Open ChatGPT Desktop → Settings → Connectors. Add a new connector. Choose "MCP server (HTTP)" as the transport.
- Paste the endpoint and token. Endpoint: https://reachout-pulse-api.usereachout.com/mcp. Authentication: Bearer YOUR_API_KEY.
- Test the connection. Ask ChatGPT "what tools do I have for ReachOut?" — it lists the surface (list_contacts, list_campaigns, get_analytics, etc.).
