Content Engine

AI-powered content creation as a service. Generate scripts, images, and videos from any topic using AI.

Built for autonomous agents. No API key or account required. Pay-per-use with USDC via the x402 payment protocol — agents can discover pricing, create content, and retrieve results in a single autonomous workflow.

Why Content Engine?

• Zero-friction for agents: No API key signup, no account creation, no subscription. Paid operations are authenticated via x402 USDC payment headers — no credentials to provision or manage
• End-to-end content pipeline: Topic in, finished video out — AI script writing, image generation, and video production in one tool
• Transparent pricing: Call get_pricing (free) to see exact USDC costs before committing. No hidden fees, no monthly minimums
• Production-ready: Deployed on Fly.io with queue management, status tracking, and daily budget controls

Billing

All paid operations use the x402 payment protocol. When a paid tool is called, the x402 proxy at CONTENT_ENGINE_URL adds a USDC payment header to the request automatically. The calling agent does not need to manage wallets, private keys, or payment credentials — x402 handles this at the transport layer. You can call get_pricing (free) to see exact costs before committing, and get_queue_status to check daily budget remaining.

Pricing

Call get_pricing at any time for live rates.

Environment Variables

Setup

Content Engine is installed and configured automatically by mcporter when you install this skill. After installation, set your environment variable:

mcporter env set content-engine CONTENT_ENGINE_URL=https://content-engine-x402.fly.dev

Verify the skill is available:

mcporter list content-engine

Available Tools

Free (no payment required)

• get_pricing — Returns live USDC pricing for all paid operations. Always call this first to confirm current rates before creating content.

  mcporter call content-engine.get_pricing
  

• get_queue_status — Check queue position, estimated wait time, active jobs, slot availability, and daily budget remaining.

  mcporter call content-engine.get_queue_status
  

• get_content — Get full details of a content item including script text, video URL, thumbnails, and metadata.

  mcporter call content-engine.get_content content_id="<uuid>"
  

• get_content_status — Lightweight status check optimized for polling. Returns current pipeline stage and completion percentage.

  mcporter call content-engine.get_content_status content_id="<uuid>"
  

Content Creation (paid via x402 USDC)

• create_script ($0.25) — Generate an AI-written video script from a topic or prompt. Accepts optional title and reference image. Returns a content_id for tracking through the pipeline.

  mcporter call content-engine.create_script topic="How AI is changing music production"
  

• create_image ($0.10) — Generate a high-quality image from a text prompt via Runway ML. Supports style directives, aspect ratios, and reference images.

  mcporter call content-engine.create_image prompt="Futuristic music studio with holographic instruments"
  

• create_video ($0.45) — Generate a full video from a content item with a completed script. Requires the content_id returned by create_script.

  mcporter call content-engine.create_video content_id="<uuid>"
  

• run_full_pipeline ($0.65) — Complete end-to-end content creation: script generation + video production from a single topic. Returns content_id for tracking. This is the fastest path from idea to finished video.

  mcporter call content-engine.run_full_pipeline topic="Top 5 AI tools for developers in 2026"
  

Typical Workflow

Quick path (single call)

get_pricing → run_full_pipeline → poll get_content_status → get_content

Step-by-step path (full control)

1. get_pricing — Confirm current USDC rates
2. create_script — Generate script from topic, save the returned content_id
3. get_content_status — Poll until script is complete
4. create_video — Generate video from the completed script
5. get_content_status — Poll until video is ready (1-5 minutes)
6. get_content — Retrieve the finished video URL and metadata

Use Cases

• Video content creation: Generate scripts and videos from any topic for use in your own publishing pipeline
• Image generation: Create AI images for thumbnails, social posts, or visual content
• Agent-to-agent workflows: Other agents can delegate content creation to Content Engine as part of larger pipelines
• Rapid prototyping: Test video concepts quickly before committing to full production

Important Notes

• Video generation takes 1-5 minutes. Always poll get_content_status rather than assuming instant completion.
• The content_id (UUID) returned by creation tools is the key for all subsequent operations.
