api record

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…

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • list_genres open 1h ago

    The genres and the most used tags of the games on Cassette, with how many games each has, and the genres of the community games. Use it to choose words for search_games, or to see what Cassette has before you promise anything.

  • search_games open 1h ago

    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.

  • similar_games unknown never probed

    Games like a given game, by the genres and tags they share (a genre counts three, a tag one). The same game always gets the same answer. Takes the same filters as search_games.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 06e483678f44a705.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/06e483678f44a705/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
80%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
