For AI agents # 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](/image-hosting-api), no browser required. [Read the docs](/docs) ### Native MCP server A remote [Model Context Protocol](/docs#mcp) 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](/docs#transforms) 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.
