Multiplayer Agent for Claude Code

Make any browser game multiplayer from Claude Code, and host it at a share link a friend can open. This plugin connects Claude Code to the hosted Multiplayer Agent backend, which provides rooms, shared real-time state, player identity, saved progress, leaderboards and game hosting, so Claude never has to write or run a game server. It also adds a make-it-multiplayer skill that teaches Claude how to design, wire, test and publish a multiplayer game on it.

No account or key is needed to start. Claude asks for your email and opens a page where you sign up or log in (your password is typed on the website, never in the chat), so your games are saved to your own account.

Install

/plugin install multiplayer-agent --marketplace natepac/multiplayer-agent

or

/plugin marketplace add natepac/multiplayer-agent
/plugin install multiplayer-agent@multiplayer-agent

If the tools don't show up straight away, type /reload-plugins. Then ask Claude something like "build me a multiplayer snake game" or "make this game multiplayer".

What it includes

  • MCP server multiplayer-agent at https://api.multiplayeragent.com/mcp (remote, streamable HTTP, no key required).
  • Skill make-it-multiplayer, used automatically when you ask for multiplayer, co-op, a lobby, an invite link, a leaderboard or hosting.

Data and privacy

The plugin sends requests to api.multiplayeragent.com: the game definitions, room settings and game files Claude creates or publishes for you, plus the email you choose to connect. Games you publish are served from *.play.multiplayeragent.com, and players' game state goes to the same backend while they play. See the privacy policy and terms.
