Tekla Structures MCP servers and AI agent skills

How AI connects to Tekla Structures

An MCP server or skill can only do what Tekla Structures lets programs do. Tekla Structures exposes 3 automation interfaces:

• Tekla Open API (.NET) (.NET): Trimble's Open API is a .NET Framework library, usually called from C#, that works alongside a running Tekla Structures with a model open. Objects are built the way the dialogs build them: a Beam takes two points, and every class shares Select, Insert, Modify and Delete. It reaches both the model and the drawing editor. All community servers here sit on this API, either in C# or through pythonnet, and load the DLLs from your own Tekla bin folder, which is why releases are version-specific. Documentation
• Macros (.cs files) (.NET): A Tekla macro is a C# source file kept in a modeling or drawings subfolder under the folders set by the XS_MACRO_DIRECTORY advanced option, or in the model folder. You can record one from the Applications & components catalog or write it in a text editor. Agents can generate these files directly, and one MCP server here lists and runs macros by file name. Documentation
• Report and drawing table templates (.rpt, .tpl) (Input files): Reports such as part, bolt and assembly lists, and drawing tables such as title blocks and revision tables, come from text template files normally edited in Template Editor. Because they are plain text with a fixed grammar and content attributes like PART.PROFILE or ASSEMBLY.WEIGHT, an agent can write them without the GUI, which is the approach of the tekla-templates skill.

What Trimble offers

Trimble ships two assistants inside Tekla Structures rather than an MCP server. Trimble Assistant for Tekla answers product questions, and its Developer Assistant helps write Open API macros from the side pane. Tekla Model Assistant, a Preview in Tekla Structures 2026 for Diamond, Graphite and Carbon subscriptions, takes natural-language requests to create objects, run clash checks and make GA drawings, and reads custom rules and skills files. Neither page mentions MCP or access from outside clients.

What you can do with Tekla Structures and AI

• Select steel or precast parts by profile, material, class or phase, then total their weight by profile or by a user-defined attribute such as a delivery batch.
• Insert or adjust connections and components, for example lifting anchors placed from a precast element's weight and centre of gravity, on the current selection.
• Run clash checks, find duplicate cast-unit or assembly numbers and flag invalid or orphaned objects before numbering and issue.
• List, update, issue, print or export drawings, and check open drawings for unmarked parts or dimensions not attached to geometry.
• Write a C# Open API macro or a report template such as a bolt list or title block, with class names checked against the Open API reference.

Installing

The listings here document setup for Claude, Claude Code, Claude Desktop, Codex, Cursor, DeepChat and Goose. Install steps, copied from each project's own documentation, are on each listing's page. Most Tekla Structures integrations run on your own computer next to Tekla Structures, so you need Tekla Structures installed and licensed on the same machine unless the listing says otherwise.
