Sage 200 + Claude

Read Sage 200 Standard and Professional through the Sage 200 API: customers, suppliers, sales and purchase orders, posted invoices, credit notes and payments, stock items and stock levels, nominal codes. Sage ID OAuth 2.0, read-only.

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:

SAGE200_PRODUCT, SAGE200_CLIENT_ID, SAGE200_CLIENT_SECRET, SAGE200_SUBSCRIPTION_KEY

Step 1 — Get credentials

Sage issues the OAuth credentials; they cannot be created inside Sage 200, so allow a few days.

  1. Request a client ID and secret from Sage Developer Services ([email protected], then Sage's application form). Ask for a confidential (web server) client with the redirect URI https://cloud.anythingmcp.com/api/mcp-oauth/callback, or <your AnythingMCP URL>/api/mcp-oauth/callback when self-hosted.
  2. In the Sage Developer Portal, copy the primary key of your Sage 200 API subscription into SAGE200_SUBSCRIPTION_KEY (sent as Ocp-Apim-Subscription-Key).
  3. Set SAGE200_PRODUCT to sage200 for Sage 200 Standard or sage200extra for Sage 200 Professional, and fill in SAGE200_CLIENT_ID and SAGE200_CLIENT_SECRET.
  4. On the connector page, click Authorize with Provider and sign in with a Sage ID that is an API user of your companies. For Sage 200 Professional, the company must be connected to the API in System Administration.
  5. Call sage_200_list_sites first: every other tool needs the site_id and company_id it returns.

The connector only reads. Lists take OData options (filter, select, orderby, top, skip) with snake_case field names. Posted invoices and credit notes are ledger transactions: read them with sage_200_list_sales_transactions and sage_200_list_purchase_transactions. A 401 means authorize again or check the subscription key and edition; a 403 means the Sage ID is not an API user of that company.

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 Claude

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.

Recommended path — works on claude.ai web without editing any config file.

  1. In Claude, open Customize → Connectors.
  2. Click +, then Add custom connector.
  3. Enter a name, e.g. Sage 200, and the remote MCP server URL https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID, then click Add.
  4. Click Connect and sign in to AnythingMCP (OAuth) to allow access.
