MCP Explained for Business Owners: How AI Connects Safely to Your ERP
Quick answer
What is MCP and why does it matter for ERP?
The Model Context Protocol (MCP) is an open standard that lets AI assistants use tools in business systems. An MCP server exposes only the actions you choose, such as checking stock or finding an invoice, with your permissions. For an ERP this means controlled access, logged actions, and write tools that still need a person's approval.
Every AI project eventually hits the same question: how does the AI get to our data? For years the answer was a custom integration for every pair of tools. The Model Context Protocol, or MCP, changes that. It is an open standard, first published by Anthropic in late 2024, that lets AI assistants connect to business systems in a consistent way. It is now supported by the major AI platforms and a fast-growing list of software vendors.
MCP in one sentence
MCP is a standard plug: you build one MCP server for your system, and any AI application that supports MCP can use it, under the permissions you set.
A simple analogy
Think of USB. Before it, every printer and keyboard needed its own port and driver. MCP does for AI what USB did for hardware. Your ERP gets one connector, and approved AI tools such as Claude, internal agents or a customer assistant can all use it.
What an MCP server for your ERP can offer
- Tools: actions the AI may take, such as look up stock for item, list overdue invoices or create draft sales order.
- Resources: read-only data the AI can consult, such as price lists, product specifications or standard procedures.
- Prompts: approved templates for common tasks, such as a month-end variance summary.
Why this matters for SAP and other ERPs
ERPs like SAP S/4HANA, Business One, NetSuite, Dynamics 365 and Odoo already have APIs. An MCP server sits on top of those APIs and exposes only what you choose, in business language. Instead of giving an AI model broad database access, you give it a short list of well-defined actions.
| Without MCP | With MCP |
|---|---|
| Custom code for every AI tool | One connector, many AI tools |
| Permissions hard to audit | Each tool and action listed and logged |
| Switching AI model means rework | Swap models without rebuilding integrations |
Keeping it secure
MCP makes connection easy, which is exactly why security design matters. The rules we apply on every project:
- Least privilege: start with read-only tools. Add write actions one at a time.
- User identity: the AI acts as the logged-in user, so ERP permissions still apply.
- Approval on writes: any action that changes money, stock or master data creates a request that a person approves.
- Logging: every tool call is recorded with who asked, what was sent and what came back.
- Trusted servers only: use MCP servers you built or reviewed; treat third-party servers like any other software supplier.
Where to start
Pick one question your team asks the ERP every day, such as "what can we ship this week?" or "which customers are over their credit limit?". Build a read-only MCP tool for it, connect it to an assistant, and measure how often people use it. That gives you a safe, visible first win and the foundation for agents later.
We build MCP servers for SAP and other ERPs, and our own ERP AI assistant follows the same approval-first design. Talk to us about connecting AI to your systems.
