Hoox Guide

The complete technical guide for freelancers who want to deliver 10 video variants at 6–8€ each — no actors, no follow-ups, no margin blowout

You're spending hours sourcing creators, rewriting briefs, and justifying budgets that no longer fly. Meanwhile, your clients want volume. This guide shows you exactly how to build an autonomous MCP with the Nano Banana Pro + Claude + Veo 3 stack to produce photorealistic UGC videos on demand — without you in the production loop.

01Step 1: Understand what an MCP is and why it changes everything for you

An MCP (Model Context Protocol) is a protocol that lets an AI agent run multiple tools in sequence, autonomously. In practice: you send it a client request, it chains the tasks without any human intervention.

For you as a freelancer, that means:

• You step out of the production loop while keeping editorial control
• You stop selling your time by the hour — you sell a deliverable output
• You can handle 5 clients simultaneously without hiring anyone

The stack you're about to build rests on 3 core components:

Before going further, create your accounts on all 3 platforms and set aside a starting budget of €50 to €100 to test your first renders.

02Step 2: Set up your Nano Banana Pro workspace

Nano Banana Pro is the conductor. It receives client inputs and routes tasks to the right tools.

First settings to configure:

1. Create a new workspace dedicated to UGC production
2. Connect your Claude instance via the Anthropic API key (Settings → Integrations → LLM)
3. Connect Veo 3 via the Google DeepMind API (or the current access available on Vertex AI)
4. Define your input variables: brand, product, tone, target duration, format (9:16 / 1:1 / 16:9)

Base workflow template to duplicate:

Initial setup time: 2 to 3 hours. After that, each new client takes 15 minutes.

03Step 3: Prompt Claude for UGC scripts that actually convert

Claude is your automated copywriter. But a bad prompt = a generic script that sells nothing. Here's the exact structure to use in your Claude node.

System prompt to integrate in Nano Banana Pro:

Dynamic variables to inject from the client brief:

• `{{brand}}` → brand name
• `{{product}}` → product name and main benefit
• `{{target}}` → persona (e.g. women 25–35, sensitive skin)
• `{{tone}}` → serious / humorous / emotional
• `{{CTA}}` → desired action (link in bio, promo code, etc.)

Always generate 3 hook variations for each brief. Run all 3 in production — you'll quickly learn which ones perform by vertical.

04Step 4: Create your photorealistic avatar in Veo 3

This is where the magic happens. Veo 3 generates videos with photorealistic human avatars from a text prompt. Not stock footage. Not a cartoon avatar. A genuine synthetic human.

Parameters to lock in once per client:

• Avatar appearance: age, gender, ethnicity, clothing, framing (bust or medium shot)
• Environment: neutral background, lifestyle interior, urban outdoor
• Lighting: natural / studio / golden hour
• Duration: 15 seconds (standard UGC format)
• Resolution: 1080x1920 (native 9:16)

Working Veo 3 prompt example:

Save these avatar profiles in Nano Banana Pro as reusable variables. One client = one avatar. You deliver consistency across every format.

05Step 5: Automate variants and deliverable organization

Your client wants 10 variants. Before, your budget only stretched to 2. Now, 10 videos cost you €60 to €80 in compute. That's where your margin explodes.

Variant workflow to configure:

1. Hook variants: 3 different scripts × same avatar = 3 videos
2. Format variants: same script × 9:16 + 1:1 = 2 formats
3. Tone variants: same script in serious + humorous versions
4. Avatar variants: same script × 2 different profiles (for A/B testing)

With this matrix, 1 client brief = 10 to 12 deliverable videos with no extra effort on your end.

Automated file organization:

Set up this folder structure as an output node in Nano Banana Pro. Zero manual organization.

06Step 6: Keep editorial control without slowing the machine down

The MCP runs on its own, but you remain the quality guarantor. That's your differentiator against low-cost agencies that deliver volume with no filter.

Your validation checkpoint (30 minutes max per batch):

• [ ] Does the hook grab attention in the first 3 seconds?
• [ ] Does the script match the brand's tone?
• [ ] Is the avatar consistent with the client's target audience?
• [ ] No visual artifacts on the Veo 3 render?
• [ ] Is the CTA clearly audible and visible?

What you never delegate to the MCP:

• Final approval before sending to the client
• Brief adjustments when the client changes direction
• Your strategic recommendation on which variants to prioritize in testing
• Your pricing — the MCP has no idea what you're worth

This human layer is what justifies charging above compute cost. You're not selling €8 videos. You're selling €800 expertise with an €8 marginal cost infrastructure.

07Step 7: Price and pitch this service to your clients

You now have an infrastructure that produces 10 UGC videos for under €100. All that's left is building an offer your clients pay at the price of their old human UGC spend.

Recommended pricing grid to start with:

Sales argument to use with your clients:

"A UGC creator charges €600 for one post. I deliver 10 testable variants for the same budget, with a consistent avatar across your entire campaign, delivered in 48 hours."

Influencer budgets are up 50% in 2026. Your clients already know the current model isn't sustainable. You show up with an alternative that actually makes financial sense.

08Key takeaways

• The MCP handles production, you handle the strategic work — brief, validation, recommendation
• One 3-hour setup lets you process every subsequent client in 15 minutes per brief
• €6 to €8 per video in real cost versus a minimum of €600 for human UGC — 30 to 50× cheaper
• 10 deliverable variants from a single client brief for under €100 in compute
• Your margin lives in the gap, not in your day rate — you're shifting from a time model to a value model
• Clients including Cheerz, Jeliskin, and Lancaster are already validating this stack in live production

You now have the complete blueprint to build this system this week. The first client brief takes the longest. The second takes 15 minutes. By the tenth, you'll barely notice it happening.
