Using the Business Central MCP in nunq

Introduction

AI works best, when it understands both your tools and your current task.

With Business Central's new MCP Server and nunq's MCP support, you can now do exactly that:

  • Use Business Central as a secure MCP server exposing ERP data and actions
  • Use nunq as an MCP-enabled assistant that already understands your on-screen context and lets users trigger assistance directly from the application they're in – including Business Central in the browser

The result: your AI assistant can "see" what the user is currently doing, call Business Central via MCP, and respond with context-aware ERP-data in one place.


MCP support in Business Central 27.1

Microsoft introduced support in Business Central at Directions EMEA last year, marking a major step towards open, standardized AI integrations with the ERP system. The announcement was shared publicly in .

Vision

The vision is to make Business Central a first-class participant in AI workflows through secure, reliable MCP tools that agents and orchestrators can seamlessly use and compose. The goal is to make all Business Central functionality available to AI and agents.

Why MCP Server for Business Central?

  • The AI future: Unlock AI-driven automation and orchestration involving Business Central
  • Standardization: Open up Business Central entities through standardized protocol, enabling seamless integration with intelligent agents
  • Business Value: Automate repetitive tasks, streamline workflows, and enable conversational ERP interactions for improved efficiency and decision-making

In other words: Business Central becomes a self-describing MCP service that AI can use to retrieve data and perform actions.

Of course, the Business Central MCP server is available to Microsoft Clients such as Copilot Studio – but now, we made it possible to also use it inside of nunq.


1. Set up MCP in Business Central

First, enable the MCP features in Business Central:

  1. Open Feature Management in Business Central
  2. Enable the features "Enable MCP Server access" and "Semantic similarity search" for all users

Then configure your MCP server:

  1. Open the Model Context Protocol (MCP) Server Configurations page
  2. Create a new configuration (e.g. Master Data)
  3. Add API pages as tools: Customers, Items, Vendors, Company Information, etc.
  4. Decide per tool: Allow Read only, or also Create / Modify / Delete / Bound Actions
  5. Enable Dynamic Tool Mode so that AI can discover actions dynamically and optionally enable Discover Additional Objects for broader access
  6. Turn the configuration Active

Once active, Business Central exposes your configuration as an MCP server that clients like nunq can connect to.

2. Add Business Central Tool in nunq

In nunq, add Business Central as a remote MCP tool:

  1. Open nunq, navigate to the Tools section and click on "Add Tool"
  2. Select Business Central from the available tool templates
  3. Configure the connection:
    • Tenant ID: Your Microsoft Entra (Azure AD) tenant ID
    • Environment Name: Your Business Central environment (e.g., ACME Corp.)
    • MCP Configuration Name: The configuration name you created in Business Central (e.g., "mcp-production")
    • Company Name: Your company name in Business Central
Business Central Tool Configuration in nunq
  1. Authenticate and configure actions:
    • After adding the tool, when you edit the tool and click on the Actions tab, you'll see the available Business Central MCP actions
    • The first time, click Authenticate and sign in with your Microsoft account used for Business Central
    • The integration will use the credentials of your Business Central user account
    • After successful authentication, you can configure which actions to enable and whether they should execute automatically

Once configured, you can optionally add other MCP servers (Jira, internal APIs, documentation) to give nunq a full view of your workflow.


3. Using the Business Central Tool in nunq

When you open nunq, you can enable the Business Central tool by toggling it on in the tool selector. This makes the Business Central MCP actions available to the AI assistant.

Now you can ask questions regarding your Business Central environment in natural language, and nunq will leverage the MCP tool to retrieve or and perform actions as needed.

Business Central Tool Calls Flow

How the tool calls work:

When you ask a question like "Based on the Item Ledger Entries in BC, what Item was the most popular in the last month?", nunq orchestrates multiple MCP calls through a dynamic discovery process:

ActionMCP Client (nunq)Business Central
bc_actions_searchPass keywords from your questionSemantic search to find top X relevant API tools/pages (e.g., Item Ledger Entries)
bc_actions_describeCall describe for further infoReturn full description + fields (schema, data types, filters, capabilities)
bc_actions_invokeCall invoke passing filtersReturn data from API page through OData protocol

This intelligent orchestration happens automatically - you just ask your question in natural language, and nunq handles the technical details of discovering, understanding, and invoking the right Business Central APIs.


Example Use Cases

1. Context-aware customer insights

User views a customer card in Business Central and clicks nunq asking:

"What are the 5 most recent sales orders for this customer."

2. Workflow support for back office

Back office staff works in a posted sales invoice list. They click nunq and type:

"For the invoice I have selected, check if there are any open delivery complaints and suggest a response to the customer."

3. Cross-system orchestration

Because nunq also integrates with tools like Jira, for example, from a Business Central error page, a user can ask:

"Create a Jira ticket with the error details and assign it to our support team."


Summary

By combining:

  • Business Central's MCP Server (a standardized, secure way to expose ERP APIs as tools)
  • nunq's MCP client and on-screen context capture (screenshot + window text in Chrome and other apps)

You get a contextual AI assistant that lives inside your existing workflows, not beside them.

Users keep working in Business Central (or any other app), tap nunq in the corner of their window, and get help that:

  • Understands what they see
  • Knows what Business Central can do via MCP
  • Acts within the boundaries you've configured

It's a practical step towards truly contextual ERP assistance – and a compelling way to bring AI into everyday Business Central work.
