dcc-itchio

Enables secure acquisition of itch.io game assets via official RSS feeds and authenticated Butler daemon downloads, and preview-gated publishing of game builds with hash-bound receipts and license verification.

README

DCC itch.io Skills

Two independently installable DCC-MCP Skills for safe itch.io asset acquisition and preview-gated game publishing.

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 AssetDescriptor with 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_KEY in 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.

Development

python -m pip install "dcc-mcp-core>=0.19.91" "pytest>=7.4,<9" "PyYAML>=6" "ruff>=0.9" Pillow
python scripts/validate_skills.py
python -m pytest -q

All network and Butler unit tests use fixtures or fake processes. CI never performs a real upload or download.
