ChatGPT & Claude (MCP)
How to Make Phone Calls with Claude
Claude can make real phone calls once Carly Teams is added as a custom connector. In Claude, press the plus sign, go to Connectors, then Add connector, then Add custom connector. Copy the Carly Teams URL from your account page on carlyassistant.com (sign in with an organization account), paste it in and press Add. Claude detects the rest, you connect your Carly account, and that's the whole setup. In the test, Claude is asked to call a cell phone and get the person to book an appointment. Claude shows the task and the number and asks for confirmation before calling. Carly's agent calls from the team's line, asks what day and time work, offers 11:30, 12:30 or 1:30 the next day from the team's calendar, and books 1:30. For a one-off you can then ask Claude to text a confirmation. Carly Teams also reads and answers your business texts, reviews missed calls and voicemail, and edits your voice and text agents from the chat. For email, calendars, files and workflows, add the Carly connector from Claude's connector directory too.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
