Connect Your Account with ChatGPT — Powered by MCP!

We’ve just launched a Custom Connector capability that lets you securely link your account with your ChatGPT account, allowing you to query your business data (Contacts, Calendar Events, and more) directly from ChatGPT — all powered by the MCP.

This update brings:

Seamless Integration Between Your Account and ChatGPT
- OAuth-Based Authentication: Ensures a secure connection between your account and ChatGPT.
- ⚙ Real-Time Data Access: Enables smarter, data-driven business conversations directly inside ChatGPT.

What You Can Do

Once connected, you can ask ChatGPT:

“Get me the list of all contacts in my account.”
“Are there any open opportunities?”
“Show upcoming appointments for tomorrow.”

ChatGPT will fetch data through MCP and summarize it instantly

Security & Compliance

Notice: This connector shares the data above with OpenAI through your ChatGPT account. By connecting, you acknowledge the risk of sharing data with OpenAI. Users with specific compliance requirements, like HIPAA, should verify their ChatGPT plan supports their needs.
Only scoped business data (Contacts, Opportunities, Calendar Events, Conversations) is accessed.
MCP doesn’t store or retain conversation data.
OAuth ensures each connection is private and revocable anytime.
