Generate Documents from Vibe (formerly Le Chat) with the Carbone MCP Connector

Generate Real Office Documents and PDFs with Vibe (formerly Le Chat) and Carbone

Vibe is Mistral's renamed Le Chat, and it ships first-class MCP Connectors. Carbone plugs straight in as one of them. Ask Vibe for an invoice in DOCX, a quarterly report in XLSX, or a pitch deck in PPTX. Carbone renders them from one JSON payload, in templates your team designed in Word, Excel, or PowerPoint, on sovereign EU infrastructure.

Why Vibe (formerly Le Chat) users choose Carbone:

First-class MCP Connector. Vibe's connector gateway makes adding Carbone a configuration step, not an integration project. Le Chat became Vibe, the MCP connector model became the standard.
Sovereign EU document generation. Carbone is a French company, and both Carbone and Mistral run on European infrastructure. Compliant by default for finance, public sector, and healthcare workloads.
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 owns the invoice, your marketing team owns the deck; Vibe 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 produces a different file every run; Carbone does not.
Battle-tested for 7+ years. Carbone powers production document workflows in finance, legal, healthcare, and the public sector.

Vibe document generation workflows: proposals, contracts, and reports

RFP responses and proposals. Vibe's Work Mode researches the prospect, drafts the response narrative, and structures the JSON. Carbone renders the branded proposal PDF with your firm's executive summary template, pricing tables, and signature page.
Board decks and strategic briefs. Vibe synthesises the source material across web and internal docs. Carbone renders the branded PPTX with your master slide layout, charts, and footer.
PRDs and engineering specs. Product teams brief Vibe. Carbone produces the branded DOCX or PDF deliverable, archived back to your knowledge base.
EU-native contracts and quotes. "A contract with parties block, conditional indemnity clause, TVA-aware French currency formatting." Vibe writes valid Carbone tags. Carbone renders the sovereign-EU output.
Bulk personalised documents. Pipe a CRM export into Vibe. Carbone renders 500 branded NDAs, employment contracts, or order forms in a single batch.
Migrate from Conga Composer, PDF Butler, JasperReports, Apache POI, Aspose, Docxtemplater, Jinja, or Handlebars. Vibe translates legacy syntax into clean Carbone tags.
Drive batch generation from the Vibe CLI. Script hundreds of branded documents from a single command.
Render directly from Le Chat or Vibe. With the Carbone MCP Connector added to Vibe, the assistant calls Carbone and returns the finished PDF, DOCX, XLSX, or PPTX in the same conversation.

Vibe to PDF: turn HTML or Markdown into a polished document

Vibe's coding mode is a strong HTML and Markdown author, and Carbone renders both as native template formats. Ask it to draft an investor report, a resume, or a product datasheet in HTML/CSS or Markdown, then hand the result to Carbone: one API call returns a print-ready PDF (or DOCX, ODT) with page breaks, headers, footers, loops, conditions, and your brand styles.

Reach for this pattern when you don't need a pre-existing Office template — one-off documents, marketing collateral, or technical brochures.

See the HTML templates and Markdown templates guides for the syntax and best practices.

Where AI-native file generation falls short

Letting an AI 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: Vibe 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 Vibe

The Carbone MCP server is the action layer — a document generation MCP for AI agents. Added as an MCP Connector to Vibe (or Le Chat, the previous name), it gives the assistant a direct line to Carbone: upload templates, render documents, convert formats, and manage your template storage, all from inside the chat.

The Carbone Skill is the optional knowledge layer. When loaded into Vibe or the Vibe CLI, it teaches the assistant the full Carbone templating language: tag syntax, formatters, conditions, loops, HTML and Markdown templates, and best practices. Together, Vibe can both design and render the document end-to-end.
