MDMagic MCP Server

MDMagic MCP Server

Convert Markdown to DOCX, PDF, and HTML using your own Word templates — your letterhead, your branding, your fonts. Plus 15 designer-built templates for when you don't have your own.

MDMagic plugs straight into Claude, Cursor, VS Code, and any MCP-compatible AI assistant — giving them direct access to a professional document conversion pipeline (Pandoc + Microsoft Graph + Mammoth.js) and, more importantly, your templates. Upload your existing letterhead, stationery, brand guidelines, contract shells, or proposal templates — anything you already use in Microsoft Word — and your AI assistant can convert any Markdown directly into a polished document carrying your logo, fonts, colours, footers, page numbers, watermarks, and signature blocks. The output looks like it came from your design team, not from a generic AI export.

You: "Take this report and turn it into an Executive_Platinum PDF."

Claude: ✅ Done. Here's your secure download link.
        14-page PDF, 2.3 MB, expires in 60 minutes.

Install

You need an MDMagic account (free tier available) and your API key from your account page.

Claude Desktop

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "mdmagic": {
      "command": "npx",
      "args": ["-y", "@mdmagic/mcp-server@latest"],
      "env": {
        "MDMAGIC_API_KEY": "mdmagic-xxxxxxxxxxxxxxxx"
      }
    }
  }
}

Config file location:

• macOS — ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows — %APPDATA%\Claude\claude_desktop_config.json
• Linux — ~/.config/Claude/claude_desktop_config.json

Restart Claude Desktop. The MDMagic tools will appear in the tool list.

Cursor

Add to ~/.cursor/mcp.json (or via Settings → MCP):

{
  "mcpServers": {
    "mdmagic": {
      "command": "npx",
      "args": ["-y", "@mdmagic/mcp-server@latest"],
      "env": {
        "MDMAGIC_API_KEY": "mdmagic-xxxxxxxxxxxxxxxx"
      }
    }
  }
}

VS Code (with an MCP extension)

{
  "mcp.servers": {
    "mdmagic": {
      "command": "npx",
      "args": ["-y", "@mdmagic/mcp-server@latest"],
      "env": {
        "MDMAGIC_API_KEY": "mdmagic-xxxxxxxxxxxxxxxx"
      }
    }
  }
}

Hosted (no install)

Don't want Node on the user's machine? Use the hosted endpoint:

{
  "mcpServers": {
    "mdmagic": {
      "url": "https://api.mdmagic.ai/mcp",
      "headers": {
        "x-api-key": "mdmagic-xxxxxxxxxxxxxxxx"
      }
    }
  }
}

Same tools, same templates, served over Streamable HTTP. Useful for clients that don't run local processes.

What you can do

Once connected, ask your AI assistant things like:

• "Convert this markdown to a PDF using the Executive_Platinum template."
• "What templates do I have available?"
• "How many credits will it cost to render this 800-word report as DOCX + PDF?"
• "Render this in landscape, US Letter, with the Legal_Burgundy template."
• "Check my credit balance."

The AI picks the right tool and returns a secure, time-limited download link.

Tools

Tool	What it does
convert_document	Convert Markdown → DOCX / PDF / HTML / all three. Returns a secure expiring URL.
validate_markdown	Pre-flight check before conversion. Catches malformed tables, unclosed code fences, and other syntax issues that would produce broken output.
estimate_conversion_cost	Pre-flight cost estimate based on word count, page count, format, and template type.
check_credit_balance	Current credit balance (subscription + purchased pools), plan status.
list_all_templates	Full template catalog: 15 built-in templates (grouped by category) + your custom uploads.
list_builtin_templates	Only the built-in templates: Business (5), Creative (6), Professional (2), Technical (2).
list_custom_templates	Only your custom uploaded templates.
get_template_details	Show available variants (page sizes × orientations) for a specific template.
recommend_template	Suggest the best built-in template for a described purpose ("Q4 board pack" → Executive_Platinum).
show_default_settings	Your default page size, orientation, and template preferences.

convert_document — input options

Three ways to provide the source:

• content — raw markdown string (most common)
• filePath — absolute path to a .md file (great for IDE workflows)
• fileContent — base64-encoded markdown (for binary-safe transports)

Plus:

• templateName — e.g. Executive_Platinum, Legal_Burgundy, or a custom template UUID
• outputFormat — docx, pdf, html, all, or all-formats
• pageSize — A4, A3, US_Letter, US_Legal, Executive
• orientation — Portrait or Landscape

Config

Variable	Default	Notes
MDMAGIC_API_KEY	(required)	Your personal API key from mdmagic.ai/account
MDMAGIC_BASE_URL	https://api.mdmagic.ai	Override only for local dev or staging
REQUEST_TIMEOUT	30000	Request timeout in ms
MCP_TRANSPORT	stdio	stdio (default) or http for self-hosted Streamable HTTP
MCP_HTTP_PORT	3001	Port for HTTP transport mode
MCP_HTTP_HOST	127.0.0.1	Bind address for HTTP transport mode

Most users will only ever set MDMAGIC_API_KEY.

Pricing

Conversions cost credits, calculated from page count and output format:

• DOCX: 1 credit per page (base)
• PDF: +1 credit per page
• HTML: +1 credit per page
• Custom templates: +1 credit per page

A 5-page report converted to DOCX + PDF + HTML using a custom template = 5 × (1 + 1 + 1 + 1) = 20 credits.

The estimate_conversion_cost tool returns exact numbers before you spend anything. The MCP also refuses to run if your balance is too low — no surprise bills.

Free-tier credits renew monthly. Paid plans and credit top-ups available at mdmagic.ai.

Privacy

• No permanent storage. Documents pass through Microsoft Graph API for PDF rendering and are deleted within 5–10 seconds. Output files are deleted from MDMagic servers after download or after 60 minutes, whichever comes first.
• Random filenames. Source files use UUIDs, never user-identifiable names.
• Secure download URLs. Each conversion returns a one-time URL with session ID and download token. No public file directories.
• API key isolation. Each user authenticates with their own key. No shared credentials.

Troubleshooting

MDMAGIC_API_KEY environment variable is required Set the env var in your client config (the env block in the JSON). Don't put it in a shell — npx won't see it.

Invalid API key format Keys must match mdmagic- followed by exactly 16 digits. Copy it cleanly from your account page.

Failed to connect to MDMagic API Check https://api.mdmagic.ai/health in a browser. If it's up, the issue is local network or firewall. Confirm MDMAGIC_BASE_URL (default https://api.mdmagic.ai) is reachable from the machine running the MCP.

Tools don't appear in Claude Desktop Fully quit and relaunch Claude Desktop after editing claude_desktop_config.json — a window close isn't enough.

Insufficient credits Use check_credit_balance to confirm balance, estimate_conversion_cost to preview costs, or top up at mdmagic.ai/account.

Local development

git clone https://github.com/MDMagic-MCP/mdmagic-mcp-server.git
cd mdmagic-mcp-server
npm install

# Set your API key (use http://localhost:3000 if running the API locally)
cp .env.example .env
# edit .env

# Build and inspect
npm run build
npm run inspector

The MCP Inspector (npm run inspector) launches a web UI for poking the server tool-by-tool — useful when adding new tools or debugging argument validation.

Run tests with npm test.
