Basecamp Claude Connector: Connect Basecamp to Claude
Yes. Add the Carly connector to Claude, connect Basecamp, and you can set up triggers right from the chat: when something happens in a project, do that. “When a client posts a message in their project, email me a summary and a draft reply.” You type it once in Claude. Carly does it for every message, whether Claude is open or not.
Where Claude and Basecamp fall short today
37signals ships an official MCP server inside the Basecamp CLI, for Claude Code and Claude Desktop. Its own issue tracker shows where it stands:
- Edits can wipe your to-dos. Changing just a to-do’s title clears every field the agent leaves out (#895).
- The hosted version won’t sign in. On mcp.basecamp.com, the Authorize button is blocked by the page’s own security settings (#873).
- Card tables break. Moving a card returns a 404 (#908), and formatted text is saved as raw Markdown.
- It only works while you chat. It runs on your computer, it isn’t in Claude’s directory, and a client message waits until someone opens Claude and asks.
How Carly fixes it
- Two minutes to set up. Add the Carly connector, sign in to Basecamp in Carly, done. No CLI to install.
- Triggers on projects. When a client posts, a to-do comes due or a project wraps, Carly acts.
- It reaches people outside Basecamp. Carly emails clients from your own inbox, texts your team and puts deadlines on their calendars.
- Thousands of apps. Carly connects Basecamp to thousands of apps, including Gmail, Outlook, Slack and Google Drive.

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."
