Claude + Basecamp: What the Integration Can (and Can't) Do in 2026
Claude can work with Basecamp — but not through a one-click app in Claude’s directory. Basecamp isn’t a first-party connector, so you connect it through a custom (third-party) MCP server built on the Basecamp API. That means a paid Claude plan, your own setup, and — like every Claude connector — it only works inside a chat you start. There are no triggers and nothing runs while you’re away.
Here’s exactly how the integration works, how to turn it on, where the limits bite, and what to use if you want Basecamp work that runs on its own.
How Claude connects to Basecamp
Unlike Notion, Slack, or Wrike, Basecamp isn’t a one-click first-party app in Anthropic’s Connectors Directory. To use it with Claude, you point Claude at a custom MCP server that talks to the Basecamp API, and add it as a custom connector in Claude’s settings.
A few things follow from that:
- It’s a custom (MCP) connector, which requires a paid Claude plan.
- You (or a developer) run the setup. A third-party or self-hosted MCP server sits between Claude and Basecamp, handling authentication to your account.
- Capabilities depend on that server. What Claude can read or change in Basecamp is whatever the MCP server exposes — there’s no official, supported feature set the way a directory connector has.
Once connected, Claude can query and reason over your Basecamp projects, to-dos, and messages inside a conversation — using natural language instead of clicking through the app.
How to set it up
The broad steps (a custom connector, so expect some setup):
- Set up a Basecamp MCP server (third-party or self-hosted) and authenticate it to your Basecamp account per its instructions.
- In Claude, open Settings → Connectors (Customize → Connectors) and add a custom connector pointing at the MCP server URL.
- Authenticate and approve access.
- Back in a chat, ask Claude about your Basecamp projects — it’ll call the MCP server.
Because custom connectors require a paid plan, this isn’t a free, flip-a-switch integration the way the directory apps are.
The limits that actually matter
Even fully set up, the integration’s shape is “an assistant you query,” not “an agent that runs your projects.” Three limits define it:
- No triggers, no automation. The connector only works inside a conversation you start. There’s no “when a to-do is assigned to me, draft the next steps” or “when a project goes quiet, nudge the team.” Nothing fires on a Basecamp event — you have to be in the chat, prompting.
- Conversation-only. Claude answers in the moment; it doesn’t sit on your account watching for changes and acting on them.
- Setup overhead. A paid plan plus a custom MCP server you set up and maintain, versus a directory connector you enable with a click.
So Claude is great for “help me understand and organize my Basecamp right now” and not built for “keep my projects moving as things happen.”
If you want Basecamp work that runs on its own: Carly
The moment you want something to happen in Basecamp without you in the chat — create a to-do the instant a request arrives, post an update automatically, follow up on a stalled project — you’ve crossed past what Claude’s connector is for.
That’s where Carly fits. Carly is an AI executive assistant built to act on triggers:
- Fires on events, 24/7, in the cloud — when an email arrives or a request comes in, Carly acts; your laptop doesn’t need to be awake.
- Connects Basecamp to the rest of your stack — create and update to-dos as part of a workflow that also touches email, calendar, CRM, and meetings.
- Actually sends and updates — drafts and sends email (Gmail and Outlook) with attachments, files and labels, manages tasks, updates your CRM, and records meetings.
- Builds the workflow for you — tell it “I’d like to set up a system that turns inbound requests into Basecamp to-dos and follows up” in plain English; it interviews you, then builds it with you. No prompt engineering, no MCP server to run.
AI agents start at $35/month, and steps in a workflow that don’t use AI run free and unlimited. Carly connects to 200+ tools across 40+ categories — see integrations and the Basecamp integration page. By the way, Carly also integrates with Basecamp.
Claude’s Basecamp connector vs Carly
| Claude (Basecamp MCP) | Carly | |
|---|---|---|
| Read projects & to-dos | Yes | Yes |
| Update to-dos | Yes (in chat) | Yes (automatically) |
| One-click setup | No (custom MCP, paid plan) | Yes |
| Acts on triggers / events | No | Yes |
| Keeps projects moving on its own | No | Yes |
| Works while laptop is closed | No | Yes (cloud) |
| Sends email as part of the flow | No (Gmail draft-only) | Yes (Gmail + Outlook) |
| Pricing | Paid plan required (custom MCP) | AI agents from $35/mo |
Claude’s connector is a strong Basecamp assistant inside a chat. Carly is a teammate that keeps your projects running.
Frequently Asked Questions
Does Claude integrate with Basecamp?
Not as a one-click app in Claude’s directory. Basecamp isn’t a first-party connector, so you connect it through a custom (third-party) MCP server built on the Basecamp API — which requires a paid Claude plan and your own setup. Once connected, Claude can query and update your projects inside a chat.
Can Claude update Basecamp automatically when something happens?
No. The connector only works inside a conversation you start — there are no event triggers. For automatic, trigger-based Basecamp actions, you need an agent platform like Carly.
How do I connect Claude to Basecamp?
You set up a Basecamp MCP server (third-party or self-hosted), then in Claude add a custom connector (Settings → Connectors) pointing at the MCP server URL and authenticate. Custom connectors require a paid Claude plan.
Is there a free Claude Basecamp connector?
Not really — because Basecamp connects as a custom MCP connector, you need a paid Claude plan plus the MCP server setup. It’s not a free, flip-a-switch directory app.
What if I want my projects to update without me in the chat?
That’s outside what Claude’s connector does — it responds inside a chat and doesn’t act on triggers. Carly fires on events 24/7 in the cloud, creating Basecamp to-dos and sending email as things happen. AI agents start at $35/month.

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."
