Overview

AI-generated overview

Lets an assistant browse, open, and rate free open-source browser games from the RIFFCADE arcade inside the chat.

What you can do
Exposes the RIFFCADE catalog of free, ad-free open-source browser games. The show_arcade tool lists games, optionally filtered by category (Puzzle, Arcade, Action, Racing, Strategy, Idle, Word & Math, 3D, Retro, 2-Player) or a search word. new_games lists recently added titles, and play_game opens a specific game by name or slug so it can be played in the chat. rate_game records a 1-5 star rating for a game.
When to use it
Useful when a user asks for the RIFFCADE, the arcade, or a game to play or browse, or wants to see what is new. It is a light entertainment add-on rather than a work tool.
Requirements
A remote MCP endpoint at mcp.riffcade.com over streamable HTTP; no packages, environment variables, headers, or authentication are declared. The assistant needs network access to that endpoint.
Before you install
rate_game writes a rating for a game, so it should only be called when the user actually gives a rating. Games open and play inside the chat, which may load third-party content from the arcade.

Installation

In SourceWeft

  1. Open RIFFCADE in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.riffcade%2Farcade/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

Score

83% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
