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.
legends_browse_standards reads open 21h ago
Browses the public Legends of Learning curriculum taxonomy. Without `standard_set`, lists the public standard sets (e.g. id "NGSS" for Next Generation Science Standards, "CCSS" for Common Core math), each with id, name, and subject_area; `query` filters them by name. With `standard_set` (a set id from the list above), lists the standards in that set. Each standard has id, code (e.g. "2.OA.A.1" or an NGSS code), title, description, grades ("k" and "1"-"12"), and subject. Use a standard's id in legends_search_games' `learning_objective_ids` to find games aligned to it. `query` free-text matches code, title, and description; `grade` (integer, 0 = kindergarten) narrows to one grade level. `page` (default 1) and `page_size` (default 10, max 25) paginate both modes. Example: {"standard_set": "CCSS", "grade": 2, "query": "addition"} finds 2nd-grade Common Core standards about addition.

Searches the public Legends of Learning game catalog (curriculum-aligned learning games for grades K-12 in math, science, and social studies). Arguments (all optional): `query` free-text matches game titles and vocabulary; `grades` narrows to games for those grade levels (integers, 0 = kindergarten through 12); `game_type` is one of "instructional", "question", or "simulation"; `learning_objective_ids` narrows to games aligned to those learning objectives (get ids from legends_browse_standards); `page` (default 1) and `page_size` (default 10, max 25) paginate. Returns `games` (each with id, title, description, image, estimated_duration in minutes, type, grades served, teacher/student ratings, and the game's public url) plus `page`, `page_size`, `total_entries`, and `total_pages`. Example: {"query": "fractions", "grades": [3, 4], "page_size": 5} finds up to five 3rd-4th grade games about fractions.
{ "type": "object", "properties": { "page": { "type": "integer", "default": 1, "minimum": 1 }, "query": { "type": "string", "description": "Free-text search over game titles and vocabulary" }, "grades": { "type": "array", "items": { "type": "integer", "maximum": 12, "minimum": 0 }, "description": "Grade levels to include; 0 means kindergarten" }, "game_type": { "enum": [ "instructional", "question", "simulation" ], "type": "string" }, "page_size": { "type": "integer", "default": 10, "maximum": 25, "minimum": 1 }, "learning_objective_ids": { "type": "array", "items": { "type": "integer" }, "description": "Learning objective ids from legends_browse_standards" } }, "additionalProperties": false }arguments 45 lineslegends_get_game reads unknown 21h ago
Fetches the full public detail for one Legends of Learning game by its numeric id (from legends_search_games). Returns the game's id, title, description, image, estimated_duration in minutes, type, grades served, teacher/student ratings, instructions, vocabulary, discussion questions, capability flags (supports_ipad, supports_tts, multi_language, saves_progress), lexile_level, the public url, and `learning_objectives` — the standards the game is aligned to, each with id, title, code, and standard_set. Example: {"game_id": 1445} returns that game, or an error result if no such game is publicly available.
{ "type": "object", "required": [ "game_id" ], "properties": { "game_id": { "type": "integer", "description": "Numeric game id, e.g. from legends_search_games results" } }, "additionalProperties": false }arguments 13 lines
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.
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.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - 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. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id3e065c2b3620311d.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/3e065c2b3620311d/claim.

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.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
