Business Central MCP: connect Business Central to Claude and ChatGPT
Ask Claude or ChatGPT which customers have overdue invoices, what a customer has bought this year or how many of an item are in stock. The answer comes straight from Microsoft Dynamics 365 Business Central.
Each person signs in with their own Microsoft work account, so the AI works within that person’s Business Central permissions, and it only reads. We set it up for your company next to your other systems.

Ask it like this
“Which customers have invoices more than 30 days overdue in Business Central?”
“What has Nordvik Bygg bought from us this year, and what is unpaid?”
“How many of item 1920-S do we have in stock?”
“Summarise what we have bought from Holmberg Stål in the last quarter.”
“Show the ledger entries on account 6110 for September.”
“Draft a friendly reminder to Erikssons Mekaniska about invoice 103045. I will send it myself.”
What we build for Business Central
Deployed OS has no ready Business Central connector yet. We build it for your company when you start, on Business Central’s own API, with the same rules as every other connector: each person’s own login, access decided by group, every call logged.
- Customers and sales invoices
- Customers, and sales invoices with their lines, amounts and due dates.
- Items and stock
- Items with their inventory and prices as the person may see them.
- Vendors and purchasing
- Vendors and what has been bought from them.
- General ledger
- General ledger entries per account and period, for the people whose role allows it.
Who sees what
- Read-only
- The connector reads. It does not post, create invoices or change a record.
- Each person’s own Microsoft login
- Everyone signs in with their work account, and Business Central applies that user’s own permission sets to every call. The person needs a Business Central licence, as they would to open it themselves.
- Your company decides who gets it
- Admins choose which groups get Business Central in Deployed OS. A group without access never sees the connector.
- Every call logged
- Who asked, what was read and when. Deployed OS keeps the log, and it can be exported.
Set up the Business Central connector in three steps
Business Central’s own MCP server or Deployed OS?
Microsoft has its own Business Central MCP Server, generally available since April 2026. Every action runs as the signed-in user with their own permissions, and by default it reads the API pages and queries that user may use. For Claude and ChatGPT you register your own Entra app. If Business Central is the only system your team wants in its AI tool, it is a good fit.
Deployed OS is for when Business Central is one system among several. It sits next to your CRM, Microsoft 365 and other tools in one company connection, admins decide which groups get each system, every call is logged in one place, and the same rules apply in Claude and ChatGPT, next to your company’s skills and guardrails.
