cad draws and modifies DXF drawings: lines, arcs, splines, hatches, dimensions, layers, blocks and AutoCAD-style commands, with a command line that runs any entry. It is still in Preview.

Under construction

This planet is still in Preview. The scaffolding is real: things here work, but expect rough edges and changes.

What your AI can do here

These are real commands from this kit’s engine. An agent sends them over the Kit Harness Protocol and gets the edited file back.

  • circleDraw a circle
  • plineDraw a polyline
  • hatchHatch an area
  • dimlinearAdd a linear dimension
  • trimTrim to an edge
  • commandLineRun any command-line entry

Use with your AI

Kition ships an MCP server for its kits. Run it over stdio against a folder, without the app open, and your agent gets tools like cad_inspect, cad_run and cad_check for every kit.

# Claude Code
claude mcp add kition -- kition-kits-mcp --workspace /path/to/your/folder

# Any MCP client (mcpServers config)
{
  "mcpServers": {
    "kition": {
      "command": "kition-kits-mcp",
      "args": ["--workspace", "/path/to/your/folder"]
    }
  }
}

The kition-kits-mcp binary comes with Kition. Without a licence key it runs in development and evaluation mode.

Questions

Is Kition cad free?

Yes. Kition is open source under Apache-2.0 and the software is free. There are no personal subscriptions, memberships or ads; you only pay for AI compute if you choose hosted AI.

Can my AI agent use Kition cad?

Yes. Every Kition kit speaks the Kit Harness Protocol (KHP), so an agent can open a file, run commands such as line, circle, and save the result. MCP connects AI to tools; KHP lets AI operate professional software.

Which files does Kition cad work with?

Kition cad saves .dxf.

Is Kition cad finished?

Not yet. Kition cad is in Preview: it works, but it is still being built and may change.
