PlayDrop Agent Plugin

Name: PlayDrop
Author: playdrop

Publish, test and share the browser games you build with your AI agent on PlayDrop. Want PlayDrop to build and maintain the game for you instead? Start with PlayDrop Cloud.

The plugin adds one skill, playdrop-ai, and a connection to PlayDrop's remote MCP server at https://mcp.playdrop.ai/mcp. Sign in to your PlayDrop account through OAuth; there is no CLI or package to install.

The public PlayDrop CLI and legacy CLI-based skills are retired. Publish games through the PlayDrop connector.

Installation covers each package in detail, with dated compatibility results.

What your agent can do

Publish index.html with its catalogue.json metadata, plus an optional icon, hero art, screenshots, a landscape trailer and a portrait teaser, localized per language.
Upload privately to test a version, then make it public from the game page. Update the same game later.
Test a running local game before uploading: open https://www.playdrop.ai/creators/<username>/apps/game/<slug>/dev?url=http%3A%2F%2Flocalhost%3A5173%2F. In ChatGPT desktop, use its built-in browser beside the conversation when available. This uses the normal PlayDrop host and SDK around your local server; no tunnel or upload is needed. Your agent checks gameplay, not just page loading. If the built-in browser blocks access to your local server, open the same Dev URL in your ordinary browser and use its local-network permission prompt. The agent reports which browser worked. The Extensions panel provides Live/Draft playback of uploaded versions.
Add the optional client SDK with one script tag: leaderboards, achievements, cloud saves, social features and multiplayer.
Run multiplayer on your own server, or upload a Colyseus server.js to PlayDrop's free hosted game servers with MongoDB. See game servers.
Send questions, bugs and ideas to the PlayDrop team with the feedback tool.

Your agent reads current limits and formats with get_documentation. Everything is also at playdrop.ai/docs.
