Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package @chanmeng666/archlang-mcp
Claude Code 
claude mcp add archlang-mcp -- npx -y @chanmeng666/archlang-mcp@0.2.29
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "archlang-mcp": {
            "command": "npx",
            "args": [
                "-y",

Floor plans as code.

Write a floor plan as text. Get a precise, dimensioned drawing back.

Send this to your agent

Paste this into any coding agent. The skills are listed on skills.sh: https://skills.sh/ChanMeng666/archlang

1. Run: npx -y skills add ChanMeng666/archlang --yes
2. Run: npx -y @chanmeng666/archlang spec   (read it before writing anything)
3. Write my floor plan as plan.arch from this brief: <describe rooms, areas, adjacencies>
4. Run: npx -y @chanmeng666/archlang compile plan.arch -o plan.svg --json
   then describe plan.arch --json, validate plan.arch --strict --json (same prefix); fix, recompile
5. Run: npx -y @chanmeng666/archlang finish plan.arch, then compile again to export.

For MCP clients: claude mcp add archlang -- npx -y @chanmeng666/archlang-mcp.

Try it

npx skills add ChanMeng666/archlang

Then ask your coding agent:

Design a one-bedroom flat of about 54 m², with the front door on the north wall.

It writes the plan, compiles it and checks it. This one is 57 lines of text:

Click the drawing to open this exact plan in the playground. Change a number and it redraws.

Why text

  • Change one number, and one thing moves. Nothing else is redrawn.
  • The same source gives the same drawing, byte for byte.
  • An agent can check its own plan without ever looking at an image.
