How to Connect Multiple Copper Accounts to Claude
Carly is how one Claude conversation reads and updates several Copper accounts. Copper doesn’t publish a Claude connector of its own, Copper GPT lives in ChatGPT and is read-only, and the third-party MCP servers each hold a single Copper login. Connect each Copper account to Carly instead, add Carly to Claude once, and Claude can create leads, log activities, move opportunities and manage tasks across your own CRM and every client’s, in the same chat.
1. Add your Copper accounts to Carly
- In each Copper account, open Settings, find API Keys and generate a key.
- Sign in at carlyassistant.com and open carlyassistant.com/integrations.
- Find Copper, click Connect, and paste the key plus the email of the Copper user who created it. Copper needs both.
- Click Connect again for the next account.
Connect Gmail, your calendar and your meeting notetaker too. That is where most CRM updates actually come from.
2. Add Carly to Claude
- Click Get the Carly connector, then Connect, and sign in with your Carly account.
- In the conversation, open + → Connectors and enable Carly.
What one chat can do afterwards
- Search people, companies, leads and opportunities across every account.
- Create and convert leads, and create opportunities.
- Log calls, meetings and notes as activities.
- Move opportunities between pipeline stages.
- Create and complete tasks and projects.
- Relate records and attach files.
Ask across all of them:
In both Copper accounts, list opportunities in Proposal with no activity in 14 days, and draft a check-in email for each one from the right Gmail address.
Why a second Copper account has nowhere to go
Copper’s own AI is built for one account at a time inside Copper: an email rewriter, contact enrichment, and Copper GPT, which brings your Copper data into ChatGPT and is read-only. There is no Copper-built Claude connector.
The routes into Claude are third-party MCP servers from marketplaces and open-source projects. They work, and each authenticates with one Copper user’s API key and email. A consultant working in four clients’ Copper accounts would need four separately vetted servers, and still couldn’t ask one question across them.
ChatGPT's event triggers keep widening, from Gmail, Slack and GitHub to other supported plugins as of September 29, 2026, and the plumbing underneath is still the hard part. A thread on OpenAI's own developer forum documents Gmail and Drive showing as authorized in Settings while conversations report them unavailable at runtime, logged from 28 August to 8 September 2026 with no public fix. Claude's scheduled tasks do not fire on events at all. Carly watches thousands of apps and acts on its own.
A CRM that keeps itself current: Carly workflows
Carly runs workflows in the cloud on a schedule or when something happens:
- Leads from anywhere. A Typeform, website form or inbound email becomes a Copper lead with the right source and owner, and Carly sends the first reply from Gmail.
- Meetings logged. After every call, Carly takes the Fathom or Zoom summary, logs it as an activity on the opportunity and turns next steps into tasks.
- Deals going cold. Every Monday at 8am, opportunities nobody touched in 14 days, with a nudge drafted for each.
- Signed means Won. When a contract comes back signed in DocuSeal or a Stripe payment clears, Carly moves the opportunity to Won and creates the onboarding project.
- Enriched before anyone looks. New leads get company details from Apollo or Hunter written into their Copper fields.

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."
