SAP Ariba MCP server

SAP Ariba is a cloud-based procurement platform connecting buyers and suppliers through the world's largest business network for sourcing, procurement, invoicing, and supplier management. With this MCP server, AI agents can manage purchase orders, execute sourcing events, track supplier performance, and access spend analytics through natural language commands.

Setting up an MCP server

This article covers the standard steps for creating an MCP server in AI Gateway and connecting it to an AI client. The steps are the same for every integration — application-specific details (API credentials, OAuth endpoints, and scopes) are covered in the individual application pages.

Before you begin​

You'll need:

  • Access to AI Gateway with permission to create MCP servers
  • API credentials for the application you're connecting (see the relevant application page for what to collect)

Create an MCP server​

Find the API in the catalog​

  1. Sign in to AI Gateway and select MCP Servers from the left navigation.
  2. Select New MCP Server.
  3. Search for the application you want to connect, then select it from the catalog.

Configure the server​

  1. Enter a Name for your server — something descriptive that identifies both the application and its purpose (for example, "Zendesk Support — Prod").
  2. Enter a Description so your team knows what the server is for.
  3. Set the Timeout value. 30 seconds works for most APIs; increase to 60 seconds for APIs that return large payloads.
  4. Toggle Production mode on if this server will be used in a live workflow.
  5. Select Next.

Configure authentication​

Enter the authentication details for the application. This varies by service — see the Authentication section of the relevant application page for the specific credentials, OAuth URLs, and scopes to use.

Configure security​

  1. Set any Rate limits appropriate for your use case and the API's own limits.
  2. Enable Logging if you want AI Gateway to record requests and responses for auditing.
  3. Select Next.

Deploy​

Review the summary, then select Deploy. AI Gateway provisions the server and provides a server URL you'll use when configuring your AI client.

Connect to an AI client​

Once your server is deployed, you'll need to add it to the AI client your team uses. Select your client for setup instructions:

Tips​

  • You can create multiple MCP servers for the same application — for example, a read-only server for reporting agents and a read-write server for automation workflows.
  • If you're unsure which OAuth scopes to request, start with the minimum read-only set and add write scopes only when needed. Most application pages include scope recommendations.
  • You can edit a server's name, description, timeout, and security settings after deployment without redeploying.

Authentication​

SAP Ariba uses OAuth 2.0 authentication. Configure OAuth in your Ariba instance to obtain credentials.

  • Authorization URL: https://{ariba-instance}/oauth/authorize
  • Token URL: https://{ariba-instance}/oauth/token
  • Client ID: Generated from Ariba admin settings
  • Client Secret: Generated from Ariba admin settings

Replace {ariba-instance} with your actual Ariba instance URL.

Tips​

Standardize requisition forms and approval workflows by setting spending limits by role, enabling electronic approvals, and tracking cycle times for optimization.

Create detailed RFx documents to get accurate quotes, evaluate suppliers systematically using scoring models, leverage competitive bidding for significant purchases, and document sourcing decisions.

Maintain accurate supplier master data by regularly updating supplier information, tracking performance metrics, and conducting periodic supplier reviews.

Reconcile invoices with POs to catch errors, match pricing to agreements, resolve discrepancies quickly, and track aging invoices.

Analyze spending patterns by category and supplier to identify consolidation opportunities, negotiate volume discounts, and track savings initiatives.
