AURA, LEO and MARIE (Virtual Companions)

AURA, LEO and MARIE are Dassault Systèmes' AI "Virtual Companions": AURA for program management, LEO for complex engineering and MARIE for deep science. Dassault announced all three as available on the 3DEXPERIENCE platform on 23 July 2026. In SOLIDWORKS 2026 FD01, LEO and AURA are reached through a SOLIDWORKS Labs (Beta) tab. Dassault's pages don't mention MCP.

Status as Dassault Systèmes states it: now available in 3DEXPERIENCE platform; SOLIDWORKS Labs (Beta) in SOLIDWORKS (LEO and AURA). Also called Dassault Systèmes Virtual Companions, AURA, LEO and MARIE.

How it relates to MCP servers

Not stated by the vendor. The Dassault Systèmes and SOLIDWORKS pages we checked don't mention MCP.

AURA, LEO and MARIE (Virtual Companions) or an MCP server with Claude, ChatGPT or Cursor?

AURA, LEO and MARIE (Virtual Companions) works inside Dassault Systèmes's own products, with the abilities Dassault Systèmes builds into it. An MCP server takes the other route: it lets a general AI assistant that you choose, such as Claude, ChatGPT or Cursor, call the software's functions, and each project decides which functions to expose.

For 3DEXPERIENCE / ENOVIA and SOLIDWORKS, Tresca lists 8 MCP servers and 1 agent skill; between them, their documentation covers ChatGPT, ChatGPT desktop, Claude, Claude Code, Claude Desktop, Codex, Cursor and Grok and other clients. See each tool page: 3DEXPERIENCE / ENOVIA, SOLIDWORKS.

Cost and licence

For SOLIDWORKS Design, tasks use Blue Tokens: Dassault gives 2,100 tokens at no additional cost as an introductory offer, not a recurring allowance, and simply chatting with a companion uses none. It needs SOLIDWORKS Design 2026 SP3.0 or later connected to the 3DEXPERIENCE platform. Token prices aren't given on that page. Source

  • 13 August 2026, SOLIDWORKS explains how Blue Tokens work for the companions. Source

AI-generated models, drawings and results must be checked by a qualified engineer before use.
