Claude + Ramp: The Official MCP, and What It Won't Do
Yes — Ramp ships an official MCP server, and it’s one of the better ones in finance. The server lives at https://mcp.ramp.com/mcp, Ramp maintains the source in its own GitHub org, and Ramp’s docs advertise one-click installation from Claude’s MCP directory. This isn’t a community wrapper around an API key.
More unusual: it writes. Claude can edit a transaction’s memo or category, approve or reject transactions, reimbursements, and requests, lock and unlock cards, create trips, and post comments. Most finance integrations stop at reading. This one signs off.
So the interesting question isn’t whether Claude can reach Ramp. It’s what happens between the moments you’re asking it things.
What the official MCP actually does
Connect it and Claude can, inside a conversation:
- Read transactions, bills, and reimbursements, and search across them.
- Edit transactions — memos, categories, trip assignments.
- Approve or reject transactions, reimbursements, and requests.
- Manage cards — lock, unlock, activate.
- Create trips and post comments, and query organizational data.
Two constraints worth knowing before you plan around it. Most of it requires Admin or Business Owner permissions — a non-admin sees a reduced toolset, so “let the team query spend in Claude” isn’t the shape unless you widen roles. And admins can restrict access further by role, department, or individual in the integration settings, which is the right call for a tool that can approve money.
Setup is either one-click from Claude’s MCP directory or adding https://mcp.ramp.com/mcp manually as a custom connector.
The gap: nothing is watching
Everything above happens because you asked. That’s the whole shape of MCP — tools Claude calls during a conversation you’re driving.
ChatGPT Scheduled Tasks and Claude Cowork both run unattended on timers. Their ordinary task schedulers do not subscribe directly to arbitrary events in connected business apps. ChatGPT Workspace Agents can be invoked through an API, but an upstream system must still detect the event and call it.
Which is an awkward fit for spend, because spend is a stream of events. The out-of-policy charge happens at 11pm on a Saturday. The receipt goes missing quietly and stays missing. The reimbursement sits in a queue until someone remembers to look. None of those announce themselves in a chat window.
So the honest split: Claude with Ramp’s MCP is excellent at “what did we spend on contractors last quarter, and approve anything under $200 that’s already documented.” It cannot do “tell me when something looks wrong.” You still have to think to ask.
The half that watches: Carly
Ramp’s MCP is the hands. What’s missing is the pair of eyes — something that notices the charge without being asked.
Carly reaches Ramp through the same developer REST API the MCP sits on, using credentials you create and can revoke. The difference is what starts the work: the event, not your prompt.
A charge posts at 11pm without a receipt. Carly catches it, checks it against your policy, emails the cardholder asking for the documentation, and if nothing comes back in three days, nudges again and flags it for you. Nobody opened a chat. Nobody remembered to look.
That’s the pattern across the rest of it too — the approval queue that gets summarized and routed instead of sitting there, the receipt chase that runs itself, the Monday digest that arrives without a Monday reminder.
What you can automate once it’s connected
With Ramp reachable through its API, an agent can handle the spend-watching and follow-up that usually falls on a finance lead:
- Flag out-of-policy spend — read new transactions, catch the ones over a threshold or missing a receipt, and email the cardholder for context.
- Chase missing receipts and memos — find transactions without documentation and nudge the right person until they’re squared away.
- Route and summarize approvals — surface reimbursements or bills waiting on sign-off and send the approver a clean summary instead of a raw queue.
- Send spend digests on a schedule — pull the week’s spend by team or category and email a rolled-up report every Monday.
- Tie it to the rest of your stack — since the same agent handles email, calendar, and tasks, a Ramp check becomes one step in a workflow, not a manual login.
How to connect Ramp to Carly
- In Ramp, open your developer / API settings and create API credentials (a client ID/secret or token; an admin may need to enable API access for your account).
- Paste your API credentials into Carly on the integrations page.
- Describe the workflow you want in plain English — “every morning, flag any transaction over $500 without a receipt and email me the list” — and Carly interviews you, then builds it.
Your credentials stay yours: you can rotate or revoke them in Ramp at any time.
Claude connector vs. no-code tools vs. Carly
| Claude (Ramp MCP) | No-code tools | Carly | |
|---|---|---|---|
| Official Ramp integration | Yes (vendor MCP) | Basic triggers | Via your API key |
| Reads transactions & spend data | Yes | Limited field mapping | Yes |
| Approves, edits, locks cards | Yes (admin roles) | No | Yes |
| Reasons over your spend | Yes, in a chat | No | Yes |
| Notices something without being asked | No | Basic field triggers | Yes, 24/7 in the cloud |
| Chases the cardholder over days | No | No | Yes |
| Sends email as part of the flow | Draft-only | No | Yes (Gmail + Outlook) |
Ramp’s MCP makes Claude a genuinely capable finance copilot — it reads, reasons, and signs off, which is more than most integrations manage. No-code tools fire fixed rules without judgment. Carly is the one that starts working before you’ve noticed there’s something to work on.
Frequently Asked Questions
Does Claude integrate with Ramp?
Yes. Ramp publishes an official MCP server at https://mcp.ramp.com/mcp, with source in Ramp’s own GitHub org and one-click installation from Claude’s MCP directory. Claude can read transactions, bills, and reimbursements, and — with Admin or Business Owner permissions — edit transactions, approve or reject items, and lock or unlock cards. What it can’t do is act on its own: MCP tools only run inside a conversation you start.
Does Ramp have an API?
Yes. Ramp offers a developer REST API with OAuth 2.0 authentication that exposes transactions, cards, users, reimbursements, and bills. You create API credentials in Ramp’s developer settings.
Do I need admin permissions to use Ramp’s MCP with Claude?
For most of it, yes. Ramp’s documentation says the majority of capabilities require Admin or Business Owner permissions; non-admin users see a limited toolset and need the right permissions for actions like approvals. Admins can also restrict access by role, department, or individual user in the integration settings.
Can Claude watch my Ramp spend and alert me?
No. The MCP gives Claude tools it calls during a conversation you start — there are no event triggers, so nothing fires when a charge posts, a receipt goes missing, or an approval lands in the queue. For spend oversight that runs without you, you need an agent that acts on events, like Carly.
How much does this cost?
Carly’s AI agents start at $35/month, and steps in a workflow that don’t use AI run free. Your Ramp API access is part of your existing Ramp account.

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."
