Updates
What's new on GameFoundry
The changelog you can actually read. New tools, MCP additions, model bumps, and the small quality-of-life wins we ship most weeks.

Bring your own Claude key, pick your model, pay only 1 credit
The Prompt-to-Browser-Game tool now lets you choose from five Anthropic models (Opus 5.5, Sonnet 5, Fable 5, Sonnet 4.6, Haiku 4.5), each with credit costs that reflect real provider cost. Or bring your own Anthropic API key and pay a flat 1-credit platform fee per call while the provider bills you directly.

Publish Godot 4 HTML5 games to GameFoundry through MCP
A new upload_godot_export MCP tool takes a Godot 4 HTML5 bundle (index.html plus .wasm plus .pck plus loader) as a single zip, unpacks it, validates it, and hosts it on R2 under your creation slot. First upload is free; re-uploads cost 5 credits.
September 15, 2026
Async jobs for long-running MCP generations
Music tracks and 3D models take 60 to 180 seconds, longer than most MCP clients wait before timing out. We switched both tools to a submit-and-poll pattern with a new get_generation_job endpoint. Long generations finish reliably now.

MCP Phase 2 is live: your agent now generates music, voice, 3D, moodboards, particles and scripts
Beyond publishing, your MCP-connected agent can now call every major GameFoundry AI tool: sprite, sfx, moodboard, voice, music, 3D model, particle effect, Godot script, Unity script, plus full browser-game generation with an auto-mint upload_id for one-shot publishing.

Every AI tool just got smarter: default model bumped to Claude Sonnet 5
The text-based tools (Godot and Unity script generation, particle designer, lore, translate, moderation, prompt-to-browser-game) all now default to Claude Sonnet 5 instead of Sonnet 4.6. Moodboard and 3D-preview both moved from SDXL to FLUX 1.1 Pro. Same tools, sharper output.
September 2, 2026
Sprite picker: FLUX 1.1 Pro, FLUX Schnell, SDXL, or Ideogram v3
The AI Sprite tool now lets you pick your image model per generation. Each option has its own credit cost, its own strengths, and its own aesthetic. Ideogram v3 is best at text-in-image, FLUX Schnell finishes in about two seconds, FLUX 1.1 Pro is our new default for quality.

My assets: every AI generation you have made, in one private gallery
A new /dashboard/assets page shows every sprite, sound effect, game, moodboard, script and 3D model you have ever generated on GameFoundry. Filter by kind, search by prompt, and jump straight back to the originating tool.

Credit packs: top up 1,000 / 5,000 / 20,000 credits, never expire
Buy credits as a one-off top-up separate from your monthly subscription. Pack credits never expire, stack on top of your monthly balance, and are perfect for a busy sprint or a heavy MCP session.
August 18, 2026
Rejected creators finally know why: moderator feedback with email
When a moderator rejects a submitted creation, they can now attach a short feedback note. The creator gets an email with the feedback and a link back to their draft so they can revise and resubmit.
August 13, 2026
Two-step uploads: publish real games, not just demos
A new start_game_upload plus finish_game_upload pair lets your agent PUT the full HTML file directly to R2, then create the draft server-side. No more hitting MCP argument size limits on real games.
August 9, 2026
One-click OAuth: connect Claude Desktop or ChatGPT with a single URL
The GameFoundry MCP endpoint now speaks OAuth 2.1 with dynamic client registration. Paste the endpoint URL into Claude Desktop or ChatGPT's custom connector dialog, click Allow, and you're publishing.
August 5, 2026
Publish AI-built games straight from Claude Code or Cursor
GameFoundry's Model Context Protocol endpoint is live. Any AI coding agent that speaks MCP can now upload a game, preview it privately, iterate on it, and submit it to the public Creations gallery without leaving the agent.
