MCP server

docjet-mcp is an MCP (Model Context Protocol) server that gives any MCP client — Claude Desktop, Claude Code, Cursor, Windsurf — the ability to render branded PDFs and PNG images. It runs locally over stdio via npx; nothing to host.

Setup

Add to your MCP client configuration:

{
  "mcpServers": {
    "docjet": {
      "command": "npx",
      "args": ["docjet-mcp"],
      "env": {
        "DOCJET_API_KEY": "binfra_your_key_here"
      }
    }
  }
}

Get a free API key at the cURL quickstart. To try it without signing up, use the public demo key (rate-limited: 3 req/min, 50 renders/month, shared):

Tools

Tool	What it does
render_pdf	Render a branded PDF. Input: template_id (or raw html) + data object. Returns a signed download URL.
render_image	Render a PNG image (e.g. OG/social card). Same input shape. Returns a signed download URL.
list_templates	List available templates: id, name, description, outputType. No API key needed.

Example prompt once connected:

“List the DocJet templates, then render the invoice-ro template with client ‘Demo SRL’ and total 1000 as a PDF.”

Environment variables

Variable	Required	Description
DOCJET_API_KEY	Yes	Your DocJet API key (binfra_ prefix). Sent as a Bearer token; never logged.
DOCJET_BASE_URL	No	Override the API base URL (default https://api.docjet.dev).

How it works

• Stdio transport using the official @modelcontextprotocol/sdk (v1).
• render_pdf → POST /v1/render?response=url · render_image → POST /v1/image?response=url · list_templates → GET /v1/templates.
• Template IDs are validated locally against ^[a-z0-9][a-z0-9-]{0,63}$ before any network call.
• API errors surface as MCP error content with the DocJet error code (e.g. QUOTA_EXCEEDED, RATE_LIMITED) — see Errors & limits.
