Introduction
Bitbybit is built to be used by AI coding agents as much as by people. Two MCP servers give an agent the exact API and hosted CAD compute; context files and Context7 cover the tools that cannot speak MCP yet.
MCP servers

Agentic CAD - our approach
Where Bitbybit geometry should run when an AI agent writes the code - the free packages first, CAD Cloud only for what needs it - and how an agent finds the exact API for the version you use.
Geometry with the kernels
How an agent writes 3D geometry with Bitbybit's kernels - OpenCascade for exact parts, Manifold for fast meshes, JSCAD for quick solids - in the browser, in the editors or in Node, how it chooses edges, checks a shape and exports it, and the mistakes to avoid.
Prompt Context Files
Learn how to use AI Prompt Context files to give your AI coding assistant comprehensive knowledge of the Bitbybit API for more accurate code generation.
Agents in the editors
The tools the Rete, Blockly and TypeScript editors on bitbybit.dev offer AI agents while they are open - through WebMCP and on the page - to search components and blocks, build and change a script in checked batches that one undo reverses, run it, read what failed and look at the result.
Design documents
How to write a Bitbybit design document - parameters, sketches, features, references that survive edits, parts and assemblies - and the validate, build and fix loop an agent should follow.
IFC building models
How an agent writes IFC4 building models with Bitbybit - storeys, layered walls with their joins, doors, windows, slabs, roofs, rooms, properties and quantities - in Node or in the browser, how it checks them, and the mistakes to avoid.
