Endless combinations
Your pipeline + any tool you use
= the decision you were missing.
Ask in the AI agent you already use. It pulls from iClosed and every tool you’ve connected, then tells you what to do next.
Asked: “Which campaigns book qualified calls, and where should next week’s budget go?” The agent read iClosed and Meta Ads, then answered: Move about $2,000 from “Free audit” to “Q3 webinar” next week.

FAQ
Questions, answered

Claude, ChatGPT and Gemini, plus any other app that supports MCP connectors. Each person connects the assistant they use with their own iClosed sign-in.
Every iClosed plan includes MCP and OAuth. There’s no add-on to buy.
Only what you approve. An assistant can ask for contacts, contact notes, calls, availability, outcomes, deals, events and team members, as read or write where each applies. iClosed’s consent screen lists exactly what it is requesting, for the workspace you choose, before you allow anything.
Access tokens last one hour and refresh automatically. Refresh tokens last 30 days and are rotated every time they’re used. You can revoke an assistant’s access anytime in Settings → Developer → Connected apps.
No. The API uses API keys and is built for developers connecting systems. MCP uses OAuth sign-in, so anyone on your team can connect their own assistant without handling a key.
