Obat API and MCP server: Let your AI agent write the quote and chase the payment.
Obat publishes no public API and no developer docs: its pricing page lists no API on any plan. Obat has no official MCP server, and no official ChatGPT or Claude connector was found. Its only outside links go to accounting: Pennylane and CSV, XLSX or FEC exports.
Obat publishes no public API and has no official MCP server (checked 14 Nov 2026). Cotlet runs a hosted Obat MCP server with 14 tools that ChatGPT and Claude use in your own Obat account. Quotes, invoices and reminders wait for your OK before they reach a client.

What can your AI agent do in Obat?
- Turn a phone call into a quote draft
- Send a quote for e-signature
- Invoice the deposit once a quote is signed
- Send the first reminder on late invoices
- Tell you what is left to collect each Monday
- Add a new client and job site
Does Obat have an MCP server or an API?
- Obat sends up to three reminders per invoice, one click each, from the "En retard" tab.
- A quote or invoice gets its definitive number only when it is finalized; drafts have none.
- E-invoicing runs through Iopole, an approved platform, on every plan.
| What you need | Obat alone | Cotlet |
|---|---|---|
| Ask ChatGPT or Claude to do the work | No API or MCP server | Hosted MCP server |
| Quotes, deposits and final invoices | By hand, one document at a time | 14 tools, sends after your OK |
| Reminders on late invoices | One click per invoice, by hand | On request or every week |
| Run from n8n or a script | No public API | REST, same key |

How does the Obat MCP server work?
- Sign in to Obat. Once, in a browser we host for you.
- Connect your AI agent. One address in its settings.
- Hand it the deposit invoices. It drafts one per signed quote, you check the amounts.
Your agent works in your own signed-in Cloud Browser. Quotes, invoices and reminders reach a client only after your OK.
How to connect Obat to your AI agent
- Sign in to Obat in a Cloud Browser. Open www.obat.fr/login in your Cotlet Cloud Browser and sign in with your own Obat account.
- Add the Cotlet address. Enter https://cotlet.dev/mcp/v1 as the MCP server or connector URL in your agent.
- Let the agent in. Chat apps open a Cotlet sign-in page. Editors, n8n and scripts send an API key made in the console.
Obat sits on the shared address https://cotlet.dev/mcp/v1 with every other app you turn on, so one connector covers them all. Turned on Obat after connecting? Refresh the connector and its 14 tools appear.

All 14 Obat MCP tools
The quote, invoice and contact screens of Obat, one tool per job. Reads and drafts run at once; the 3 tools that email a client ask first.

Who can see my Obat session, and how do I revoke it?
- What we store. Your signed-in Obat browser profile, AES-256-GCM encrypted, in Finland. Never your password.
- What your agent gets. The 14 Obat tools. The session cookie stays in the Cloud Browser.
- What the session sees. The quotes, invoices, clients and job sites your account and plan show, and nothing more.
- What no tool touches. Your Obat password, email and subscription, the Compte Pro and bank connection, the Pennylane link and accountant access, e-invoicing settings, and deleting any document.
- If Obat signs you out. You sign in again yourself, in the same Cloud Browser.
- How to cut access. Disable Obat for agents, reset the browser, or change your password.
You type your Obat password yourself; the agent only uses the session that sign-in leaves behind. Our site scores A+ on Qualys SSL Labs, securityheaders.com and Mozilla Observatory (live results).
What happens when Obat changes?
The tools work through the pages you use in Obat, so an update to those screens does not stop your quotes and invoices. Cotlet watches the apps it serves and updates the Obat server when Obat changes.
New Obat features become available to your agent. It still sees only what your own account and plan can see.
Cotlet never sees or stores your password. If Obat signs you out, one click in the Cotlet console reopens the Cloud Browser so you can sign in again.
Approvals, undo and mistakes
- Find signed quotes. list_quotes reads the Devis list.
- Draft the deposit. create_invoice_from_quote saves it, no number.
- Show you the draft. get_invoice: lines, percent and total.
- Send after your OK. send_invoice numbers and emails it.
| Action | How to put it right |
|---|---|
| Client or job site added | Remove it by hand in Contacts or Chantiers |
| Quote or invoice draft | Delete the draft in Obat; it had no number and reached nobody |
| Quote sent | Already with your client: tell them, then send a corrected quote |
| Invoice sent | Numbered and locked: Obat cancels it with a credit note (avoir) |
| Reminder sent | Already with your client: follow up with them directly |
The 3 tools that email a client (send_quote, send_invoice, send_invoice_reminder) ask first: by default you confirm each call, and you can switch that off per tool. The other 4 write tools only save drafts, clients and job sites, which reach nobody, and the 7 read tools run at once.

Obat MCP server: other ways to connect
| Option | What it does | Where it stops |
|---|---|---|
| Obat AI voice quotes | A paid option (29 € excl. VAT a month on the pricing page) that drafts a priced quote from your voice, text, a photo or a PDF. | It drafts quotes inside Obat; sending, invoicing and reminders stay with you. |
| Zapier, Make, n8n | No Obat app on Zapier or n8n, and none found on Make. | Nothing to trigger or act on in Obat. |
| Official API | None published; no plan on the pricing page lists one. | Nothing to build on. |
| Pennylane link, CSV, XLSX, FEC exports | Send finalized documents, purchases and payments to your accounting. | Accounting only: no quotes, invoices or reminders. |
| By hand | Open each quote and invoice and click through. | Only while you are at the screen. |
Only Cotlet lets your agent do the daily Obat work on every screen you use, reading and writing, from ChatGPT, Claude or any MCP client, with no API key from Obat and on your current plan.
Who runs Cotlet
Take Group sp. z o.o. makes Cotlet. It is a software company registered in Poland, EU (VAT PL6342984273), working since 2019, founded by Bart Krawczyk (Co-founder, CTO) and Jake Slugocki (Co-founder, SEO, sales and marketing). Questions about the Obat tools go to contact@cotlet.dev.
Obat MCP server: questions
How do I get access?
Sign up free at https://cotlet.dev/signup?app=obat, turn on Obat under Integrations in the console and sign in at https://www.obat.fr/login in your Cloud Browser. Then connect your AI agent and ask it which invoices are late. The trial needs no card.
Does my Obat plan limit what the agent can do?
Yes, because the agent works in your own account and sees what your plan shows. Per the pricing page, purchasing, job-site profitability and time tracking start at the Croissance plan, and the planning for teams of 2 to 50 is there too. Quotes, invoices, clients and reminders are in every plan.
Does this replace the Pennylane connection?
No. Obat connects finalized invoices to Pennylane on its own (Pennylane Essentiel plan or higher), and exports files for other accounting software. Cotlet works on the quote and invoice screens. It does not touch your accounting link or your accountant access.
Which Obat user should I sign in with?
The user whose quotes and invoices the agent should handle. Obat sells extra user licences for staff, and the agent sees only what the signed-in user can see.
Can the agent write quotes and emails in French?
Yes. Your clients read French, so ask for French line labels and email text, or write the prompt in French. The tools keep Obat's own words, such as Devis, Factures and En retard.
Is the MCP server different from the REST API?
Only in how it is called. Both carry the same 14 tools, inputs, answers, API key and price. Agents use MCP; scripts and n8n HTTP steps use REST.
Is Cotlet affiliated with Obat?
No. Cotlet is independent and not affiliated with Obat.
