Hellbox (formerly Font Proof) is a macOS app for type designers that generates PDF font proofs and live-reloads them from Glyphs and RoboFont.\n\nThis package launches the MCP server that ships inside the [Hellbox](https://hellbox.com) app bundle. The server lets AI tools create and edit `.fontproof` documents directly; the app does not need to be running.\n\n## Requirements\n\n- macOS 12 or later\n- [Hellbox](https://hellbox.com) installed (the server binary ships inside the app)\n- Node.js 18+ (for `npx`)\n\n## Setup\n\nThe easiest path is Hellbox's built-in one-click setup: open Hellbox, go to Preferences, then AI Integration, and click the installer for your client. To set it up manually instead:\n\n### Claude Code\n\n```bash\nclaude mcp add font-proof -- npx -y font-proof-mcp\n```\n\n### Claude Desktop\n\nAdd to `~/Library/Application Support/Claude/claude_desktop_config.json`:\n\n```json\n{\n  \"mcpServers\": {\n    \"font-proof\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"font-proof-mcp\"]\n    }\n  }\n}\n```\n\n### Cursor\n\nAdd the same `command` / `args` pair to `~/.cursor/mcp.json`.\n\nIf Hellbox is installed somewhere other than `/Applications` or `~/Applications`, set `FONT_PROOF_MCP_PATH` to the full path of `Hellbox.app/Contents/Helpers/font-proof-mcp`.\n\n## Tools\n\n- **Documents:** `create_proof`, `create_complete_proof`, `open_proof`, `get_proof_info`, `open_in_app`\n- **Sections:** `add_section`, `update_section`, `delete_section`, `reorder_sections`, `duplicate_section`, `set_section_content_bulk`, `update_section_settings`\n- **Fonts:** `add_fonts`, `remove_fonts`, `list_system_fonts` (variable font axes supported)\n- **Glyphs 3:** `list_glyphs_fonts`, `add_glyphs_fonts`\n\nFull documentation: [hellbox.com/docs](https://hellbox.com/docs) under \"MCP Server\".\n\n## How it works\n\nThe MCP server is a Swift binary embedded in the Hellbox app at `Contents/Helpers/font-proof-mcp`, codesigned with the app and always in sync with the app's document format. This package is a thin launcher: it finds that binary and hands over stdio. No server logic is duplicated here, so the tools you get always match the app version you have installed.\n\nThe package keeps the `font-proof-mcp` name from the app's Font Proof era; the npm name, the server name MCP clients see, and the `.fontproof` file extension are all stable across the rename.\n\n---\n\nHellbox is made by [Minim Industries](https://hellbox.com).\n",
