PixelVault — Image Hosting for AI Agents

Agent skill for image hosting: upload an image and get a permanent CDN URL back — from Claude Code, Codex, Cursor, or any agent that reads SKILL.md.

PixelVault is agent-first image hosting for developers and AI coding agents. This skill lets an agent upload screenshots, diagrams, mockups, and generated images and get an instant, globally-cached CDN URL — no manual dashboard, no drag-and-drop, no copy-paste.

When it triggers: "screenshot this and host it", "upload this image and give me the URL", "attach this diagram to the PR", "host this mockup", or any task that produces an image needing a shareable link.

Why PixelVault for agents

• Just an API key — no crypto wallet, no per-upload payment. A permanent free tier, not a trial.
• Permanent, global URLs — served from Cloudflare's edge CDN with zero egress fees.
• Built for discovery — ships a Claude Code skill, a remote MCP server, llms.txt, and an OpenAPI 3.1 spec so any agent can find and call it.
• Works with any agent — Claude Code, Codex, Cursor, Gemini CLI, or paste SKILL.md into custom instructions.

Skills

Skill	Description
/pixelvault-upload <file>	Upload image(s) and get CDN URLs
/pixelvault-setup	Install CLI and configure API key
/pixelvault-list	List recently uploaded images

Quick Start

npx skills add pixelvault-dev/skill

Then, inside your agent:

1. Run /pixelvault-setup to configure your API key
2. Upload images with /pixelvault-upload screenshot.png

Use it from any agent

• skills.sh (any agent) — npx skills add pixelvault-dev/skill installs the skill folders for Claude Code, Codex, Cursor, and more.
• Claude Code plugin — install from the marketplace, or copy the folders in skills/ into .claude/skills/ (project) or ~/.claude/skills/ (user).
• Remote MCP server — point any MCP-capable agent at https://mcp.pixelvault.dev/mcp (bearer auth with your API key). No local install required.
• Any other agent — paste a SKILL.md from skills/ into your custom instructions, or hand the agent the OpenAPI spec below.

How It Works

The skill wraps the PixelVault CLI. When you (or an agent) upload an image:

1. Image is uploaded to PixelVault's edge infrastructure
2. Stored on Cloudflare R2 (zero egress fees)
3. Served globally via Cloudflare CDN
4. You get a permanent URL like https://img.pixelvault.dev/proj_abc/img_xyz.png

Requirements

• Node.js 20+
• A PixelVault account — free tier: 200 MB storage, 500 uploads/month, 1 GB bandwidth, 5 MB max file size. No credit card, no trial expiry.

Examples

> /pixelvault-upload screenshot.png
Uploaded: https://img.pixelvault.dev/proj_abc/img_xyz.png

> /pixelvault-upload *.png --folder diagrams
Uploaded: https://img.pixelvault.dev/proj_abc/img_001.png
Uploaded: https://img.pixelvault.dev/proj_abc/img_002.png

> /pixelvault-list --json
[{ "id": "img_xyz", "url": "https://...", "size": 45200, ... }]

Agent discovery

PixelVault is designed to be found and used by agents without a human in the loop:

• MCP server — https://mcp.pixelvault.dev/mcp
• llms.txt — pixelvault.dev/llms.txt
• OpenAPI 3.1 spec — api.pixelvault.dev/openapi.json
• API catalog (RFC 9727) — pixelvault.dev/.well-known/api-catalog
