tekla-mcp

MCP server for AI control of Tekla Structures — 3D structural modeling, drawing automation, and BIM workflows.

By Hugo Velasco - dualitum.com

Overview

Tekla MCP connects Claude (or any MCP-compatible AI client) directly to Tekla Structures via the Tekla Open API, enabling AI-driven 3D modeling, member creation, drawing extraction, and BIM automation.

Architecture

Claude / AI Client
       | MCP (stdio)
       v
  Python FastMCP Server (server.py)
       | Tekla Open API (.NET)
       v
  C# Bridge (TeklaMCPClean.csproj)
       |
  Tekla Structures (running instance)

Requirements

• Windows (Tekla Structures is Windows-only)
• Tekla Structures (any recent version with Open API support)
• Python 3.11+
• .NET SDK (for C# bridge compilation)

Installation

cd Server/TeklaMCP
pip install -r requirements.txt

Build the C# bridge:

dotnet build TeklaMCPClean.csproj

Usage

Add to your Claude Desktop claude_desktop_config.json:

{
  "mcpServers": {
    "tekla-mcp": {
      "command": "python",
      "args": ["path/to/Server/TeklaMCP/server.py"]
    }
  }
}

Tekla Structures must be open and running before starting the server.

Capabilities

• 3D Modeling: Create and modify beams, columns, braces, and connections
• Drawing Automation: Extract and manage Tekla drawings
• Model Query: List and search model objects, get geometry and properties
• BIM Workflows: Export/import structural data
