Archlang MCP

Text in, a precise architectural drawing out. Deterministic, zero-dependency, and built so an AI agent can verify its own plan without ever looking at an image. It runs locally over stdio via the published package.

People connecting developer tools tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Archlang MCP

Claude Code

claude mcp add chanmeng666-archlang -- npx -y @chanmeng666/archlang-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "chanmeng666-archlang": {
      "command": "npx",
      "args": [
        "-y",
        "@chanmeng666/archlang-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
