Agent Designer and MCP: Building Custom AI Agents Inside Business Central

Microsoft opened up agent creation to everyone, and added Model Context Protocol support. Here's what that combination actually enables — and where it pays off.

Two changes in Business Central deserve more attention than they've had. Individually they're interesting. Together they change what an ERP can be asked to do.

Interactive example: Email orders that create themselves. An order arriving by email becomes a draft sales order: the agent identifies the customer, matches the products to the catalog, applies their price list and flags the line it does not recognise for review. A person approves it. Open the demo

Agent Designer: agents without a development project

Until recently, an AI agent in your ERP was something Microsoft shipped or a partner built from scratch. Agent Designer changes that: custom agents can be created directly inside Business Central, connected to your data, defined using natural language alongside AL code.

You define how the agent behaves, what data it can reach, and how it interacts with your processes. The prototyping loop that used to take a development cycle now takes an afternoon.

That's a meaningful shift. It means automation can follow how your organization actually works rather than how a generic template assumes it works.

MCP: connecting Business Central to the wider AI world

Model Context Protocol support is the part you won't see in the interface, but you'll feel if you build anything. MCP is an open standard for how AI systems connect to tools and data sources. In Business Central it makes integration with Copilot Studio and custom AI substantially easier.

Wave 1 brought further improvements to the Business Central MCP Server, including configuration validation.

Put plainly: your ERP becomes something external AI can safely and reliably talk to — with proper structure, rather than brittle glue code.

Where this actually pays off

The temptation is to build agents for everything. Don't. The processes worth automating first share three traits:

Good candidates we see repeatedly: overdue invoice follow-ups, purchase order exception handling, document categorisation, inter-company reconciliation, and inventory anomaly flagging.

Poor candidates: anything requiring genuine judgement, anything with legal or safety consequences if it goes wrong, and anything that happens rarely.

The part people underestimate

Building the agent is the easy half. The hard half is governance: who reviews what the agent did, what happens when it's wrong, how you audit its decisions, and where the human checkpoint sits.

The new agent task pane helps by consolidating agent activity in one view, but you still need to decide the process rules. An agent operating without a review path is a liability, not an asset.

Where to start

Pick one high-volume, rule-based process. Measure what it costs you today in hours. Build one agent. Measure again. Then decide whether to expand.

That sequence — measure, build one, prove it — is how this becomes real savings rather than an interesting experiment.

Let's identify which process in your business is the right first agent.

FAQ

What is MCP in Business Central? A server that lets AI tools and agents query and act on Business Central data with your permissions — the bridge between your ERP and AI assistants.

Do custom agents need a developer? Agent Designer covers a lot without code. Anything touching custom data or logic needs AL work.

Already on Business Central? If you're reading this because nobody has told you what each release brings, which agents you could switch on or why your Power BI is still empty, you don't need a migration: changing partner is a 30-day handover, not a project.
