PlayDrop Agent Plugin

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 when your agent asks; there is no CLI or package to install.

Install

• Claude Code: /plugin marketplace add playdrop-ai/playdrop-plugin, then /plugin install playdrop@playdrop.
• Codex: codex plugin marketplace add playdrop-ai/playdrop-plugin, then install PlayDrop from the Plugins Directory.
• Grok Build: grok plugin install 'playdrop-ai/playdrop-plugin#variants/grok/playdrop' --trust.
• Antigravity: clone this repository, then agy plugin install ./playdrop-plugin/variants/antigravity/playdrop.
• Replit: add PlayDrop to Replit.
• Gemini web, iOS and Android: add a custom app on Gemini web, then use the same Google account on mobile. Requires an eligible personal US account, age 18+, English and Keep Activity enabled. See the Gemini guide; consumer runtime validation is pending.
• ChatGPT, Claude, Lovable, Grok and other MCP clients: add a custom connector with the URL https://mcp.playdrop.ai/mcp and OAuth.

PlayDrop Connector has a step-by-step guide for each platform:

• Agents with plugins: Codex, Claude Code, Antigravity.
• Hosted assistants: ChatGPT, Claude, Lovable, Replit, Grok, Gemini.

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 inside PlayDrop before publishing: https://www.playdrop.ai/creators/<username>/apps/game/<slug>/dev?url=http://localhost:5173/.
• 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.
