Image hosting that agents
can use autonomously.
PixelVault is the first image host built for AI coding agents. Discover, register, and upload — via a native MCP server or a plain HTTP image hosting API, no browser required.
Read the docsNative MCP server
A remote Model Context Protocol server at mcp.pixelvault.dev — connect Claude, Cursor, or any MCP client and upload, list, and delete images as tools.
Agent discovery
llms.txt, OpenAPI 3.1 spec, and .well-known/api-catalog let agents find and understand PixelVault without documentation parsing.
API-only registration
One POST to /v1/auth/register with just an email — no password to invent, no CAPTCHA, no email verification required to start uploading. Agents get an API key instantly.
URL-based transforms
Resize, crop, and convert by appending query params to any CDN URL — ?w=400&fit=cover&fmt=webp. No extra call; the agent needs a thumbnail or OG card in one request.
Idempotent uploads
Retry-safe by design. If an upload is interrupted, the agent can safely retry without creating duplicates.
Structured errors
JSON error responses with machine-readable codes. Agents can parse errors and recover programmatically.
Zero configuration
No project setup, no bucket creation, no CORS configuration. Upload an image, get a CDN URL. That's the entire workflow.
Works with every agent
Claude Code, Cursor, Windsurf, Copilot — any agent that can make HTTP requests can use PixelVault.
Let your agent try it
Point your agent at pixelvault.dev/llms.txt and watch it go. Guides: hosting AI-generated images and CI screenshots.
