dcc-itchio
Provides tools for safe itch.io asset acquisition and preview-gated game publishing: browse the official game-assets RSS feed, list and inspect owned asset projects and Butler channels, download an exact owned upload after license verification, and perform authenticated Butler pushes with hash-bound preview receipts and revalidation.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@dcc-itchiodownload the asset 'Synthwave Starter Kit' I own on itch.io"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
DCC itch.io Skills
Two independently installable DCC-MCP Skills for safe itch.io asset acquisition and preview-gated game publishing.

Illustration generated for this repository; it contains no third-party logos, copied marketplace thumbnails, or product UI.
Skills
itchio-assets
Browse only itch.io's official game-assets RSS feed.
List and inspect asset projects with direct download-key ownership on the authenticated account through the official Butler daemon API.
Download one exact owned upload without running installers or downloaded code.
Require explicit license evidence before any download, then return a validated DCC-MCP
AssetDescriptorwith hashes and attribution.
This Skill does not buy assets, scrape project pages, infer a license from price or ownership, or import downloaded content into a DCC application. Version 0.1 fails closed for bundle-only ownership.
itchio-publish
List projects owned by the authenticated creator account.
Inspect Butler channels and their head/pending build states.
Create a hash-bound preview receipt for a prepared game build.
Revalidate the source tree, license provenance, Butler binary, channel parent, and preview result before an authenticated
butler push.
Publishing consumes license-provenance.json produced by the marketplace
game-release-package Skill. Core's asynchronous job cancellation terminates
the local Butler process only; it is not a remote build rollback.

Runtime requirements
DCC-MCP Core 0.19.91 or newer
Python 3.7 or newer for production scripts
itch.io Butler 15.30.0 or newer
BUTLER_API_KEYin the local environment for authenticated operations
The API key is never accepted as a tool argument, written to a receipt, placed on a command line, or returned in tool output. The asset Skill passes it to an ephemeral, isolated Butler daemon over JSON-RPC and removes that daemon's local state after the request.

PyPI status: not published
This repository is an agent skill pack, not a distributable Python package.
It contains no importable module under src/ — the deliverable is the set of
markdown skill definitions under skill/, which agents load from the repository
or the skill marketplace rather than via pip install.
It is therefore intentionally not published to PyPI, and no release workflow exists for that purpose. Tracked in PIP-3630.
