Overview

Description from the maker (original English)

Make any browser game multiplayer and host it at a share link. No account needed to start.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Web & browsers
  • You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • You fill in yourself: Authorization

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http multiplayer-agent 'https://api.multiplayeragent.com/mcp?src=registry' --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "multiplayer-agent": {
      "url": "https://api.multiplayeragent.com/mcp?src=registry",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "multiplayer-agent": {
      "type": "http",
      "url": "https://api.multiplayeragent.com/mcp?src=registry",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • Authorization secret HTTP header
    Optional. Bearer : the studio secret key, starting sk_, from https://multiplayeragent.com/dashboard/key. Without it, the agent connects the session to an account through a browser sign-in, or builds…

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Multiplayer Agent safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.2) reached the registry 9 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Browser Use, Chrome DevTools MCP, MCP Server Browser

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

Type these in Claude Code:

/plugin marketplace add multiplayeragent/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.
