Generate Documents from Claude with the Carbone Skill and MCP
Generate Real Office Documents and PDFs with Claude and Carbone
Claude is one of the strongest file-creation models among the major AI assistants, with first-class Agent Skills and MCP support. Carbone plugs straight into both. Ask Claude for an invoice in DOCX, a contract in PDF, a quarterly report in XLSX, or a pitch deck in PPTX, and Carbone renders it from one JSON payload, in templates your team designed in Word, Excel, or PowerPoint.
Why Claude users choose Carbone:
- Design templates in the tools you already use. Word, Excel, or PowerPoint — or HTML, Markdown, or even a fillable PDF form if you prefer. No proprietary editor and no code-only templating syntax like Handlebars or Jinja to learn. Your finance team edits the invoice, your marketing team edits the deck; Claude fills in the data.
- 100+ output formats. PDF, DOCX, XLSX, PPTX, ODT, ODS, CSV, HTML, Markdown, JPEG, PNG. Real editable Office files, not screenshots embedded in a DOCX wrapper.
- Deterministic and predictable at scale. One Carbone template plus one JSON payload produces the exact same document every time, at predictable subscription pricing — not a per-token bill. AI-native file generation is expensive in tokens and changes every run; Carbone does not.
- The only open Skill plus MCP combo. The Carbone Skill teaches Claude Carbone's templating syntax (loops, filters, formatters, conditionals). The Carbone MCP server lets Claude render and convert documents directly from the chat. Use either, or both together.
- Works in Claude Code, Claude Desktop, and Claude.ai Projects. Install once, available everywhere Claude is.
- Battle-tested for 7+ years. Carbone powers production document workflows in finance, legal, healthcare, and the public sector.
Claude document generation workflows: contracts, invoices, and reports
- Legal contracts and M&A due diligence. Claude is the model corporate lawyers reach for: clause comparison, redline review, deviation flagging from typical positions. Pair it with Carbone: Claude drafts the contract and Carbone renders the final DOCX with your firm's branding, clause library, and signature blocks.
- Master Service Agreement libraries. Let Claude draft a master template with hourly, project, and retainer variants. Carbone renders the personalised version for each new client in minutes.
- Invoice and quote generation at scale. "An invoice with line items, conditional VAT row, total in euros, hide the VAT line for exempt customers." Claude writes valid Carbone tags on the first try. Carbone renders thousands per hour.
- Accounting firm workflows. Engagement letters, audit reports, advisory deliverables. Claude drafts the narrative, Carbone produces the branded DOCX, XLSX, and PDF outputs your clients expect.
- Long-document summarisation to polished output. Claude condenses a 50-page agreement into a tight brief. Carbone renders the brief in your firm's executive-summary template.
- Migrate from Conga Composer, PDF Butler, JasperReports, Apache POI, Aspose, Docxtemplater, Jinja, or Handlebars. Claude translates legacy syntax into clean Carbone tags.
- Fix and improve existing templates. Paste a broken Carbone tag into Claude Code, get a working one back. No support ticket.
- Render directly from the chat. With the Carbone MCP, Claude calls Carbone and returns the finished PDF, DOCX, XLSX, or PPTX in the same conversation.
Claude to PDF: turn HTML or Markdown into a polished document
Claude Code is exceptional at writing HTML and CSS. Ask it to design a one-page resume, a product datasheet, a quarterly investor report, or a landing-page-style proposal in HTML, then pass the result to Carbone to render it as a print-ready PDF. Carbone handles page breaks, headers, footers, and your brand styles, all from a single API call. The same handoff works for Markdown: Claude writes the structured content, Carbone converts it to a polished PDF, DOCX, or ODT.
This pattern is the right fit when the output does not need a pre-existing Word template, for example one-off documents, marketing collateral, or technical brochures. Claude handles the design and the copy, Carbone handles the print-ready conversion.
See the HTML templates and Markdown templates guides for the syntax and best practices.
Where Claude's native file generation falls short
Letting Claude build the whole file is great for a one-off draft. For production document workflows, three things break, and Carbone fixes each:
✗ Not repeatable. The same prompt yields a different file each run, with layout, fonts, and branding drifting from page to page, so testing, versioning, and automation fall apart.
✓ Carbone renders the same document every time from one template and one JSON payload.
✗ Fragile, locked-down files. AI output can look fine yet refuse to open cleanly, break its own formulas, or flatten tables and text into images you cannot edit.
✓ Carbone fills a real Office template instead of writing the file from scratch, so every result is structurally valid and fully editable.
✗ Expensive at scale. Generating full documents burns tens of thousands of tokens each, and a small edit regenerates large sections.
✓ Carbone uses predictable pricing instead — a fixed document quota, usage-based billing, or a flat rate for unlimited rendering.
Bottom line: Claude helps you draft the template and the wording; Carbone handles the part that has to be exact — merging your data to produce the same document every time.
Carbone Skill and MCP: render documents from Claude Code and Claude Desktop
The Carbone Skill is the knowledge layer. It teaches Claude, in Claude Code, Claude Desktop, or Claude.ai Projects, the full Carbone templating language: tag syntax, formatters, conditions, loops, :set patterns, HTML and Markdown templates, and best practices. Once installed, Claude writes correct Carbone templates on the first try.
The Carbone MCP server is the action layer — a document generation MCP for AI agents. Through the Model Context Protocol, Claude can call Carbone directly to upload templates, render documents, convert between formats, and manage your template storage, all from inside the conversation.
Use the Skill on its own to design and fix templates. Add the MCP when you want Claude to render the finished document end-to-end, without leaving the chat.
