01 · Install Bitbybit CAD MCP

Claude Code

claude mcp add bitbybit-dev-bitbybit --transport http https://mcp.bitbybit.dev/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "bitbybit-dev-bitbybit": {
      "url": "https://mcp.bitbybit.dev/mcp"
    }
  }
}

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

Using another client? Same JSON, different key
