Adding the arnold™ MCP Connector in Copilot Studio via Dynamic Client Registration (DCR)

Dynamic Client Registration (DCR) is a simplified onboarding process that allows a Microsoft Copilot Studio agent to securely connect to arnold™ without requiring administrators to manually create Client Apps in the arnold Portal ahead of time.

Step 1: Add Agent Instructions​

To ensure proper SAP data handling and secure tool usage, configure the agent instructions as follows:

  • Only use the arnold™ MCP tools for all SAP data retrieval.
  • Do not assume or fabricate information. All responses must come directly from tool calls.
  • Display returned data in a clear, readable format.
  • Provide a SUMMARY for each response that explains the returned data.

These instructions enforce tool-based retrieval, prevent hallucinations, and standardize output formatting.

Step 2: Add the MCP Connector​

Before You Begin​

To successfully use DCR, an administrator must already have:

  • Admin access to the arnold™ Portal
  • At least one SAP Connection configured in the arnold™ Portal

MCP Connector Configuration​

Configure the connector with the following values:

  • Server URL
    your portal URL followed by /mcp https://na.arnold.enosix.com/mcp

  • Authentication Type

Authentication Mode​

By default, the MCP connector uses End-user credentials.

  • Each user must authenticate individually before accessing SAP data.
  • This ensures user-level security, traceability, and audit logging.
  • All activity is logged under the individual user in arnold™ Portal.

For testing or controlled demo environments, you may switch to:

Maker-provided credentials

  • The agent accesses SAP using a shared credential.
  • Individual user authentication is not required.
  • All SAP logs in arnold™ Portal will appear under the shared credential.

Use Maker-provided credentials only for non-production or controlled testing scenarios.

Tool Management​

To control the scope of the agent:

  1. Open the Tools section.
  2. Review the dynamically discovered tools.
  3. Disable any tools not required for this specific agent.

Example:

  • material_search_by_group
  • material_search_by_type
  1. Click Save.

Restricting tools improves security and reduces unintended tool invocation.

  1. Click See agent in Microsoft 365 to open it.

Step 7: Add and Share the Agent​

  1. In Microsoft 365, click Add.
  2. Once installed, the agent appears under Agents in the left menu.
  3. Hover over the agent, click More, then select Share.
