Reer

AI CAD agent with open-source MCP server integrations

AI-powered CAD agent that connects designers to multiple CAD platforms (Rhino, Revit, Blender, Fusion 360, etc.) through Model Context Protocol (MCP) servers. Enables Claude and other AI agents to directly control CAD software via natural language.

Why This Tool Exists

The Problem

Architects and engineers spend 60%+ of CAD work on repetitive, non-creative tasks like object placement, parameter adjustments, and scene manipulation. Manual CAD workflows waste hours per day across design teams.

The Solution

Reer provides open-source MCP server integrations that connect Claude AI and other LLM clients directly to CAD applications. Designers interact with their CAD tools via natural language, while AI handles code generation and model manipulation behind the scenes.

Algorithm
How it works
Model:Claude (via MCP) or other LLM clients with MCP support
Accuracy:Not publicly specified
Privacy
How your data is protected
Retention:Not publicly specified (inferred: local-first model execution on user machine via MCP)
Training:Model Context Protocol is designed for isolated data; customer CAD files not used for training LLM
Compliance:GDPR compliant (inferred from open-source nature and privacy-first MCP architecture)
API
Integration
Endpoint:Model Context Protocol (MCP) server endpoints (specific URLs per CAD platform)
Method:MCP protocol (two-way communication via local server)

Use Cases

  • ·Automate repetitive CAD tasks using natural language (object placement, parameter sweeps)
  • ·Accelerate schematic design iteration by generating design variations via prompt
  • ·Create parametric models and GHPython automations through conversational interface
  • ·Perform scene analysis and metadata extraction from complex 3D models
  • ·Multi-CAD workflow automation (Rhino to Revit translation assistance)
  • ·Design documentation generation with AI-assisted visualization
