About the MCP connector

An MCP connector is a universal interface that can connect to any MCP (Model Context Protocol) server and dynamically invoke its available tools through a standardized protocol. You point the MCP connector at any MCP-compatible server, authenticate once, and call the tools that server exposes from your RPA, API Workflow, and Maestro automations.

For guidance on when to use the MCP connector versus configuring an MCP server directly, see the frequently asked questions. To learn more about the Model Context Protocol itself, see the MCP documentation.

Note:

The MCP connector is in Preview. Depending on your tenant, you may need to enable it through the Integration Service connector catalog policy in UiPath® Automation Ops before it appears in your connector list.

Authentication

Before you can invoke tools, you must establish a connection to your MCP server. The MCP connector supports OAuth 2.0 and token-based authentication. Step-by-step instructions are available on the MCP connector authentication page.

Activities

You use the connection to build automations that discover and run the tools exposed by the connected MCP server. For more information, see the MCP connector activities page.

Frequently asked questions

When should I use the Integration Service MCP connector instead of configuring an MCP server in Orchestrator directly?

The correct path depends on the type of automation:

  • Deterministic automations — RPA, API Workflows, and Maestro processes that follow a fixed, predefined path — consume the Integration Service MCP connector directly. The author chooses the specific tool to run, and Integration Service handles authentication, connectivity (direct or Automation Relay), and governance.
  • Non-deterministic automations — coded agents and low-code agents that decide at runtime which tools to call — consume MCP servers created in Orchestrator.

Either way, the connection is created once in Integration Service, so credentials, OAuth, Relay, and governance are managed centrally regardless of which surface consumes it.
