How to Connect SAP Business One to ChatGPT — via MCP

💡 No install? Use cloud.anythingmcp.com directly. Sign in, click Connectors → SAP Business One, paste your credentials, mint an MCP API key — done. No Docker, no git clone, no local server.

SAP Business One + ChatGPT

Drive SAP Business One ERP (popular Mittelstand SMB target in DACH) from any AI agent: business partners, items, sales orders, A/R invoices, quotations, deliveries. Service Layer OData v4. Session-cookie auth via /Login.

Prerequisites

See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:

SAP_B1_HOST, SAP_B1_PORT, SAP_B1_COMPANY_DB, SAP_B1_USERNAME, SAP_B1_PASSWORD

Step 1 — Get credentials

Setup:

1. Identify your Service Layer host (typically the same machine that runs HANA + SAP B1). Default HTTPS port is 50000.
2. Create or pick a B1 user that has API access for the company database you want to expose.
3. Find the CompanyDB name in Choose Company dialog of the B1 client (looks like SBODEMOGB).
4. Set the five env vars below. The adapter logs in once per session (~25 min TTL) and re-uses the B1SESSION cookie.

OData: this adapter targets the v2 / OData v4 Service Layer endpoint at /b1s/v2/. Older /b1s/v1/ (OData v3) deployments are not covered — upgrade to FP 2405+ first.

Step 2 — Install the adapter

curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d

Step 3 — Add the connector in ChatGPT

Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide shows YOUR_SERVER_ID.

ChatGPT connects to MCP servers as custom apps in developer mode, available on paid plans (not on Free). On Business and Enterprise workspaces an admin may have to allow it first.

1. In ChatGPT, open Settings → Security and login and turn on Developer mode.
2. Go to chatgpt.com/plugins and click +.
3. Enter a name and a short description, e.g. Name: SAP Business One.
4. Under Connection, enter the MCP server URL https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID and create the connection.
5. When ChatGPT asks, sign in to AnythingMCP (OAuth) and allow access.

FAQ

Does the free ChatGPT plan work with custom MCP connectors? No. Custom MCP connections need developer mode, which is only on paid plans.
