README

TeklaMCP

A Model Context Protocol (MCP) server for Tekla Structures, enabling AI assistants (Claude, Cursor, etc.) to read and modify your structural model through natural language.

What it does

TeklaMCP runs as a WPF desktop application alongside Tekla Structures. It exposes a local HTTP server (http://127.0.0.1:51234/) that speaks the MCP protocol — so any MCP-compatible AI client can place beams, query objects, delete elements, and more, all by calling into the live Tekla model.

MCP Tools

Tool Description
PlaceBeam Place a beam between two 3D coordinates
PlaceBeams Place multiple beams in a single call
PlaceColumn Place a column at a base point with a given height
ModifyBeam Modify profile, material, position, or endpoints of an existing beam
FilterModel Query model objects by type, name, profile, material, class, or user-defined attributes
GetUserSelection Read the objects currently selected by the user in Tekla
UserSelectedBeam Prompt the user to pick a beam and return its properties
DeleteObject Delete a single object by GUID

OverlappingNumbering Find parts with duplicate cast-unit or assembly numbers

MCP Resources

Resource URI Description
tekla://model/object-names Distinct list of all part names in the model
tekla://model/grids All grid objects with coordinates and axis labels

Requirements

  • Windows (WPF desktop app)
  • Tekla Structures 2023 or later, with a model open
  • .NET Framework 4.8
  • An MCP-compatible AI client (Claude Desktop, Cursor, etc.)

Usage

  1. Open a model in Tekla Structures.
  2. Launch TeklaMCP (TeklaMcp.Server.exe).
  3. Click Start — the server starts at http://127.0.0.1:51234/.
  4. Configure your MCP client to connect to that URL.

Claude Desktop (claude_desktop_config.json)

{
  "mcpServers": {
    "tekla": {
      "url": "http://127.0.0.1:51234/"
    }
  }
}

Health check

GET http://127.0.0.1:51234/health

Returns {"status":"ok"} when the server is running.

Audit log

Every tool call is appended to:

%APPDATA%\Develoh\Tekla\mcp-audit.log

Each line is a JSON object with timestamp, tool, args, success, and message.
