# Bonsai MCP > Create and inspect architecture projects in the Bonsai MCP Harness workspace, including its local starter and optional upstream integration. - Skill: `autonomous-ai/bonsai-mcp` (Agent Skill) - Install (CLI): `npx skillmds@latest add autonomous-ai/bonsai-mcp` - Raw SKILL.md: https://api.skillmd.com/api/skills/autonomous-ai/bonsai-mcp/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: AI & ML - Author: autonomous-ai (https://skillmd.com/u/autonomous-ai) - Updated: 2026-09-21 - Page: https://skillmd.com/skills/autonomous-ai/bonsai-mcp --- # House of ideas Read `studio.json` to understand the current controls; `"$STUDIO_TOOLCHAIN/../studio.config.json"` describes their ranges. Run `"$STUDIO_TOOLCHAIN/run.sh" build` to make a new result. Successful artifacts and their measurements are in `out/runs//`; `out/latest.json` names the current result. A failed run preserves the last success and records the error in the verdict. The local workflow creates and reopens a real IFC4 building with IfcOpenShell, including storeys, slabs, walls, spaces and quantities. The in-pane drawing is a schematic model inspector. It does not certify structural adequacy or code compliance. Blender/Bonsai editing remains available through the pinned optional bridge. Use `"$STUDIO_TOOLCHAIN/../README.md"` for the integration contract and commands. Read the relevant files under `$STUDIO_UPSTREAM` before using an upstream API. Keep controls within their documented ranges, preserve the data needed to reproduce a comparison, and distinguish preview results from native service or hardware output. The viewer supports history and artifact downloads; tell the user which run contains the result, and what was actually measured. ## Author and check building data Choose the footprint, storeys, height, and room use, then run `build`. Reopen `building.ifc` with IfcOpenShell, inspect spaces/walls/openings, and read the quantity sets. Match their areas and volumes to `quantities.csv`. The canvas is a schematic view; IFC is the source artifact for downstream editing. Preserve element identifiers when extending an existing model. Read `$STUDIO_UPSTREAM/docs/examples.md` for Bonsai edits and read-back verification, `docs/installation.md` for the bridge, and `docs/tools.md` before native commands. The wrapper's `bonsai` action only requests scene information from an existing Blender session.
