StudioMCPHub

Creative AI tools and art datasets for autonomous agents.

StudioMCPHub is a production MCP server offering 32 tools (18 free): image generation, upscaling, background removal, product mockups, CMYK conversion, print-ready PDF, SVG vectorization, invisible watermarking, AI metadata enrichment, provenance registration, permanent Arweave storage, NFT minting, and access to 53,000+ museum artworks from Alexandria Aeternum. Agents pay per call with x402 USDC on Base L2 — no API keys, no accounts, no sign-up.
