How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 3 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability64
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 842 tokens (~280/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage86
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 58% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
How do I install the Legends of Learning MCP server?
Legends of Learning is a hosted endpoint at https://app.legendsoflearning.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
legends_browse_standards Browse curriculum standards ~333
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.
| Name | Type | Req | Description |
|---|---|---|---|
| grade | integer | – | Only standards for this grade level; 0 means kindergarten |
| page | integer | – | – |
| page_size | integer | – | – |
| query | string | – | Free-text filter (set names, or standard codes/titles/descriptions) |
| standard_set | string | – | A standard set id (e.g. "NGSS", "CCSS"); omit to list the sets |

legends_get_game Get a Legends of Learning game ~161
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.
| Name | Type | Req | Description |
|---|---|---|---|
| game_id | integer | yes | Numeric game id, e.g. from legends_search_games results |
No output schema declared.
No examples provided.
legends_search_games Search Legends of Learning games ~311
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.
| Name | Type | Req | Description |
|---|---|---|---|
| game_type | string | – | – |
| grades | array | – | Grade levels to include; 0 means kindergarten |
| learning_objective_ids | array | – | Learning objective ids from legends_browse_standards |
| page | integer | – | – |
| page_size | integer | – | – |
| query | string | – | Free-text search over game titles and vocabulary |
