Overview

AI-generated overview

Remote MCP server with creative image tools — upscaling, background removal, mockups, print prep, watermarking — plus museum artwork search and metadata…

What you can do
  • Discover and inspect tools by category, price or keyword before loading schemas
  • Process images: upscale, resize, remove background, extract palettes, vectorize to SVG, convert sRGB/CMYK, prepare print-ready files, place designs on product mockups
  • Embed, detect and verify invisible watermarks and perceptual hashes; enrich and infuse image metadata
  • Search and retrieve 53,000+ public-domain museum artworks, including deep visual analysis and bulk download
  • Store, list, retrieve and delete assets in a personal wallet storage area
  • Register a wallet, check credit balance and fetch compliance manifests
When to use it
Useful when an assistant needs to prepare or transform images for e-commerce, print or design work, add provenance and metadata to artwork, or pull public-domain museum images and their descriptions. The free tools make it easy to trial before paying.
Requirements
Remote streamable HTTP endpoint; no local install, API key or account needed. Paid tools require payment per call via x402 USDC on Base L2, Stripe card payment with an API key, or prepaid GCX credits; a wallet registration grants 10 free GCX. Self-hosting is possible from source with Python and environment variables.
Before you install
Most non-trivial tools cost money per call (for example $0.20 upscale, $5.00 bulk download), and agents can spend without a sign-up step, so set spending limits. Payments use USDC on Base L2 or card details. Tools write, overwrite and delete data in wallet storage, and metadata embedding, hash registration and watermarking alter images. Uploaded images and metadata are sent to a third-party service.

Installation

In SourceWeft

  1. Open Studiomcphub in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.codex-curator%2Fstudiomcphub/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Add this to your client's mcpServers config.

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.

Quick Start

One-click install for Cursor:
