IFC MCP

Clear the already-open local IFC viewer by removing all loaded IFC files and BCF viewpoint state. This keeps the same stable viewer URL and does not close the browser tab. Use show-ifc-file after this to load a fresh IFC model.

Open or show the local IFC viewer and return its stable viewer URL. This tool does not load IFC files and does not change selection/isolation state. After this tool returns, use the returned URL as the viewer address. If the client can open links, open that local URL; otherwise tell the user to open the URL in a browser or webview. Use show-ifc-file to show IFC files. Use set-bcf-view to apply a BCF viewpoint file. Do not use browser automation to click or select elements in the viewer.

Execute LLM-created Python in the SDK Node/Pyodide IFC runtime. Use this tool for IFC inspection, validation, reports, exports, and creating new IFC files. Runtime context: Pyodide uses the bundled Pyodide 0.28.2 runtime. The package set includes micropip, ifcopenshell, numpy, pandas, matplotlib, shapely, and typing-extensions. The Python code is passed directly to the SDK. File inputs: pass IFC/IFCXML/IFCZIP file paths in the files array. In the desktop Node server these are local filesystem paths; in a browser host they are browser-defined paths resolved by that host. Generated Python can open those files by name, e.g. ifcopenshell.open("model.ifc") or open("model.ifc", "rb"). Return contract: this tool exposes stdout, stderr, saved_files, uploaded_files, and any result returned by the raw SDK. Generated files are returned as temporary localhost download URLs in saved_files. Do not assume files were written to the user's working directory.

Set the view state in the already-open local IFC viewer by applying a BCF/BCFZIP viewpoint file. Pass either a local BCF/BCFZIP file path or a generated BCF download URL from run Python saved_files. This tool does not show/load IFC files; use show-ifc-file for that. It should not open a new browser tab and should not use browser automation. To generate a BCFZIP with run-python, write a .bcfzip file, then call set-bcf-view with saved_files[0].url: ```python from uuid import uuid4 import ifcopenshell from bcf.v3 import model as mdl from bcf.v3.bcfxml import BcfXml from bcf.v3.visinfo import VisualizationInfoHandler model = ifcopenshell.open("sample.ifc") gid = model.by_type("IfcWall")[0].GlobalId component = mdl.Component(ifc_guid=gid) visinfo = mdl.VisualizationInfo( guid=str(uuid4()), components=mdl.Components( selection=mdl.ComponentSelection(component=[component]), visibility=mdl.ComponentVisibility( default_visibility=False, exceptions=mdl.ComponentVisibilityExceptions(component=[component]), ), ), ) bcf = BcfXml.create_new(project_name="IFC MCP") topic = bcf.add_topic("Review wall", "Review wall", "ifc-mcp", topic_type="Issue", topic_status="Open") topic.add_visinfo_handler(VisualizationInfoHandler(visinfo)) bcf_path = "view.bcfzip" bcf.save(bcf_path) print(str(bcf_path)) ```

Show one IFC file in the already-open local IFC viewer. Pass either a local IFC/IFCXML/IFCZIP file path or a generated IFC download URL from run Python saved_files. Use this for IFC model display only. Repeated calls add multiple IFC files to the same viewer. Returns the same stable viewer URL; after this tool returns, use that URL as the viewer address. Use open-ifc-viewer to open the viewer and set-bcf-view to apply a BCF viewpoint file.
