# Kiln (MCP server)

> Kiln is an MCP server that adds developer tools to AI assistants such as Claude Desktop, Claude Code and Cursor. Build and revise procedural 3D assets with your coding agent. It has 237 GitHub stars, is released under the MIT license and runs locally with npx -y @instruktlabs/kiln.

Build and revise 3D assets with your coding agent. The package name is @instruktlabs/kiln. This checkout targets version 1.0.0. Stable releases use npm's latest tag; release candidates use next. Until 1.0.0 is available in the npm registry, install the public RC with npm install @instruktlabs/kiln@next, or pin @instruktlabs/kiln@1.0.0-rc.1. Do not use the unqualified name while latest still points to the temporary 0.0.0-stage holding version.
