Nothing serious here today

Today is the operative word: we check Legends of Learning every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

legends

legends_browse_standards

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.

legends_get_game

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.

legends_search_games

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.

Legends of Learning — questions

Answers built from our own checks of this server.

What can Legends of Learning do?

It exposes 3 tools, read directly from the server on our last check. Among them: legends_browse_standards, legends_get_game, legends_search_games. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Legends of Learning working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 523 ms. The bar chart above shows every period we have measured.

How do I connect Legends of Learning?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Legends of Learning need an API key?

No. Legends of Learning completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Legends of Learning?

It answers our handshake in 523 ms on average, which is faster than 22% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
