About getdigitalcraft-mcp-render

getdigitalcraft-mcp-render generates social images from specifications for AI agents and returns PNGs with exact text. It uses deterministic HTML-to-SVG rendering rather than an image model, with per-call USDC payments and no account or API key.

Key features

  1. 01Render social images from specifications
  2. 02Support ten platform image formats
  3. 03Offer single-image and platform-bundle rendering
  4. 04Produce identical pixels from identical inputs
  5. 05List formats without payment

Use cases

  1. 01Create social images with exact headlines
  2. 02Generate image sizes for several platforms in one call
  3. 03Check supported formats before rendering

MCP support

The MCP server provides image-rendering and format-listing tools. Paid renders are settled per call in USDC over x402 on Base; payment is signed locally, and format lookup works without a key.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

Environment variables to set
X402_PRIVATE_KEYSecretPrivate key of a wallet holding USDC on Base. Used locally to sign x402 payments; it never leaves your machine. Without it the server still starts and lists tools, but rendering is disabled.

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Details

From the project README

getdigitalcraft-render (MCP)

Deterministic social image rendering for AI agents. Spec in, PNG out, with typography that is exactly the text you asked for — image models still garble lettering; this cannot, because it isn't a model. Paid per call in USDC on Base over x402, so there is no account, no API key and no subscription.

  • render_image — one format, $0.03
  • render_bundle — a whole platform set in one paid call ($0.75–$2.00)
  • list_formats — free, makes no payment

Ten formats: Instagram square / portrait / story, Facebook feed, Open Graph, X card, LinkedIn, Pinterest pin, YouTube thumbnail, quote card.

Install

{
  "mcpServers": {
    "getdigitalcraft-render": {
      "command": "npx",
      "args": ["-y", "getdigitalcraft-mcp-render"],
      "env": { "X402_PRIVATE_KEY": "0x..." }
    }
  }
}

X402_PRIVATE_KEY is your wallet, holding USDC on Base. It never leaves your machine — this server signs payments locally and sends only the authorization. Use a wallet funded with what you're willing to spend on rendering, not your main one.

Without the key the server still starts and list_formats still answers; only paying is disabled.

Why it's deterministic

satori renders HTML to SVG, resvg rasterises it. No diffusion, no GPU, no sampling — so the same spec always yields the same pixels, and the headline you pass is the headline that appears. Roughly 250ms warm.

Cost

$0.03 per image, $0.75–$2.00 per bundle, settled in USDC on Base. Nothing is charged if the render fails.

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
