Cassette Game Finder MCP

A read-only MCP server provided by Cassette that allows AI agents to search for browser games, retrieve game details, find similar titles, and filter by genres. It enables agents to assist users in discovering games hosted on the Cassette platform without requiring authentication.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Cassette is a store of games that run in the browser. Use these tools to help a person find one. When the request already gives you something to search with (a device, an age, a mood, a game they liked), search first and ask afterwards what would narrow it; ask first only when it gives you nothing. Put the person's own words in `query` and their limits (device, age, price, multiplayer, download size) in the filters. Read each game's facts before you recommend it, offer one to three games with their play links and what could stop the person (a keyboard, an account, a big download), and if nothing fits, say so: never suggest a game these tools did not return. Community games are listed from other sites and play there. These tools only find games; to publish, use the separate server at https://cassette.gg/mcp/publish (sign-in required, a person approves).

search_games — Search games

Advertised by the server during the last successful anonymous check.

Advertised read-only

Find games on Cassette that fit what a person wants. Every game comes with facts (devices, players, session length, age rating, download size, whether an account is needed and whether saves follow the player), its store page and a link that opens it. Returns hosted games first, then community games from other sites. An empty result is an answer: tell the person nothing fits.
