| Application | Coupa |
| Category | Accounting |
| AI tools | 62 |
| Authentication | App credentials |
| Bring your own OAuth app | No |
| MCP endpoint | https://api.elaichi.ai/mcp |
| Works with | Claude, ChatGPT, Cursor, any MCP client, and the Elaichi Agent |
| Tools advertised by name | No. Connected tools are never listed one by one, however few there are. The endpoint advertises `search_tools` and `execute_tool` instead |

## What you can ask once Coupa is connected

- Show me open requisitions waiting for a purchase order
- Which suppliers invoiced us this month and for how much?
- Create a requisition for 20 standing desks from Steelcase

## Connect Coupa in Elaichi

This happens once for the organization, before any client is involved.

1. Open Connections, choose Add connection, and pick Coupa.
2. Optionally set Share with, then press Connect.
3. Paste your Coupa app credentials. Coupa authenticates the app rather than a person. One person supplies the credentials once, and everyone else works through Share with.

Credentials are vaulted and nobody, including the AI, reads them back. The connection becomes a toolbox immediately, so you can curate which Coupa tools are exposed, rename them, or freeze arguments before anyone points a client at it.

2. Sign in and approve.

The Elaichi Agent already has these tools, with nothing to set up.

## What the consent screen decides

Every scope the client asks for starts ticked except "Delete data and remove access", which you tick yourself. Calling a Coupa tool needs "Run your connected tools". Over MCP there is no trusted place to confirm a write in the moment, so the consent screen is the standing approval rather than a formality. Think hard before granting Run your connected tools, which can also delete in connected apps and cannot be undone.

## What teams do with Coupa through Elaichi

### Raise a requisition from a team's request

Procurement. Turn a request for new laptops into a Coupa requisition with the right items and supplier, without opening the form yourself.

### Match an invoice to its purchase order

Accounts payable. Pull up a supplier's invoice and the purchase order behind it side by side to check quantities and amounts before it is paid.

### See what is committed with each supplier

Finance. List open purchase orders by supplier and currency to understand spend commitments before month end close.

### Onboard a supplier and keep details current

Supplier management. Add a new supplier to Coupa and update contact or payment details when they change, straight from the chat.

Operations. Search Coupa items and supplier items to check what is already on contract and at what price.

### Check where a requisition is stuck

Office management. Ask which requisitions are still waiting and who raised them, then chase the right person.

## Elaichi vs Zapier MCP vs Composio for Coupa

## Frequently asked questions

### How do I connect Coupa to Claude?

Connect Coupa in Elaichi first: Coupa uses app credentials, so you paste the credentials your Coupa administrator issues, with no OAuth application to register and no client ID or secret to generate. Then open Claude, go to Customize, then Connectors, then Add, and paste the endpoint https://api.elaichi.ai/mcp. Claude asks you to sign in to Elaichi, and from then on it can work with your Coupa requisitions, purchase orders, suppliers and invoices.

### Does Coupa work with ChatGPT and Cursor as well as Claude?

Yes. Once Coupa is connected in Elaichi, the same endpoint, https://api.elaichi.ai/mcp, works in Claude, ChatGPT, Cursor, any other MCP client and the Elaichi Agent. You connect Coupa once and every client you use picks it up.

### What can an AI agent actually do with my Coupa data?

It can look up Coupa requisitions, purchase orders, invoices, suppliers, catalog items and accounts, and answer questions like which invoices arrived from a supplier this month or which requisitions are still open. It can also raise a new requisition or purchase order, add a supplier, and update a supplier's details or an open requisition. Short, concrete asks work best, such as 'list open requisitions over 5,000' rather than a long paragraph.

### Does connecting Coupa give the AI every purchase order and invoice in the company?

No. The connection carries the access of the Coupa app credentials it was set up with, and each person signs in to Elaichi as themselves, so an agent sees only the Coupa requisitions, orders, suppliers and invoices that access allows. Elaichi can narrow that further by team or by action, and it can never widen it beyond what Coupa itself permits.

### Can my team share one Coupa connection?

Yes. One person connects Coupa in Elaichi and shares the connection with a team, and nobody else ever handles the app credentials. Each teammate still signs in as themselves, so every Coupa call in the audit log names the person who made it, not the person who connected it.

### Can I stop an agent from deleting or changing things in Coupa?

Yes. Restrictions in Elaichi work per action, so you can allow reading Coupa invoices and purchase orders while blocking the ability to delete a requisition or change a supplier. A restricted action is left out of the AI client's tool list entirely, so it cannot be called no matter how the prompt is phrased.

### What happens to a Coupa connection when someone leaves?

Offboarding a person in Elaichi ends their access to Coupa through every AI client at once. If they had shared a Coupa connection with a team, it keeps working for everyone else. If you want it gone entirely, disconnecting Coupa once in Elaichi removes it from Claude, ChatGPT, Cursor and every other client at the same time.

### Does the Coupa MCP connector work with Gemini, Codex, Claude Code or other MCP clients?

Yes. Coupa is reached over the same MCP endpoint every client uses, so anything that speaks MCP can call it — Gemini, Codex, Claude Code, Windsurf, Cline, Zed and OpenCode among them — alongside Claude, ChatGPT, Cursor, and the Elaichi Agent. The tools on offer and the access behind them are identical whichever client asks. Only the setup screen differs.

### Is Elaichi an alternative to Zapier MCP for Coupa?

Yes. Both let Claude, ChatGPT or Cursor use Coupa. Zapier MCP fits a team that already automates in Zapier, since each person signs in and acts as themselves in that account. Elaichi fits when IT wants one address for the whole company, per-tool rules by role, and a record of every Coupa call.

### How is Elaichi different from Composio for Coupa?

Composio gives AI agents tools and sign-in handling across 1,000+ apps, for developers building agents or people using an assistant, billed per tool call. Elaichi gives a company's own people governed access to Coupa: one address, restrictions per role or user, and $15 per user per month. Both have role permissions and a log of every call.
