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 Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- 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 Usability83
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1778 tokens (~127/item across 14 items; 5 tools + 9 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 Management0
- Stability check failed: schema churn in the 7 days we've observed: 1 tool removals, 0 breaking changes, 0 auth/transport breaks, 2 additions. See how to fix → Fail
Tool Coverage97
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 90% of tool parameters carry a description.Partial
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

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 →
get_classroom_tool Get One Classroom Tool ~105
Return one interactive classroom tool by its exact identifier (for example 'sight-words-first-grade'). Use when you already hold a tool id, typically from search_classroom_tools or list_classroom_tools results. Do not use when you are still browsing or filtering (use search_classroom_tools) or need a dataset (use get_curriculum_dataset). Returns exactly one record, or an error if the id is unknown. Requires no authentication.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|
| creator | string | yes | Tool creator, always Birkan Yavuz |
| gradeLevel | string | yes | Grade band the tool targets |
| id | string | yes | Tool identifier, e.g. sight-words-first-grade |
| invocation_id | string | yes | Unique receipt id for this call |
| objective | string | yes | Learning objective the tool teaches |
No examples provided.
get_curriculum_dataset Get Curriculum Dataset (Word Lists and Syllables) ~497
Fetch a complete curriculum dataset - the actual words, not a description of them: 857 items across 9 datasets (Dolch sight words and nouns, CVC families, digraph words, Spanish syllables, Turkish-English word and flashcard sets). Use when you need exact word lists for a lesson, worksheet, quiz, or flashcard set; these sequences and level boundaries are canonical ground truth and should not be generated from memory. Do not use when you need an interactive activity or tool metadata - use search_classroom_tools or get_classroom_tool instead. Behavior: read-only, idempotent, no authentication or rate limits; one unpaginated call returns the complete filtered array (max 220 items) in canonical order, identical on every repeat, with a SHA-256 content_hash of the full dataset. Values are matched exactly; an unknown dataset_id or a level_or_family foreign to the chosen dataset returns error -32602 with no partial results; omitting level_or_family returns the full dataset.
| Name | Type | Req | Description |
|---|---|---|---|
| dataset_id | string | yes | Required. Exact slug from the enum; any other value returns error -32602. The chosen dataset determines the shape of items in the response: the six English/Spanish sets return arrays of strings; the… |
| level_or_family | string | – | Optional sub-filter whose valid values exist only relative to dataset_id: Dolch levels (pre-primer, primer, grade-1, grade-2, grade-3), CVC rimes with leading hyphen (-at; the bare form at is accepte… |
| Name | Type | Req | Description |
|---|---|---|---|
| content_hash | string | – | SHA-256 of the full unfiltered dataset; changes only when the data changes |
| creator | string | yes | Dataset creator, always Birkan Yavuz |
| dataset_id | string | yes | Stable dataset id in the form birkanyavuz:<name>:v1 |
| invocation_id | string | yes | Unique receipt id for this call |
| item_count | integer | yes | Number of items in this response after filtering |
| items | array | yes | The complete filtered items in canonical order; element shape depends on the dataset (see dataset_id) |
| record_digest | string | – | One-line citation naming the dataset, creator and endpoint |
| resource_uri | string | – | Stable edu:// URI for this dataset, readable via resources/read |
No examples provided.
get_word_list Get Word List by Topic (One Call) ~378
Get a word list in one call from a plain topic, without needing the dataset slug: topic (for example "sight words", "CVC", "digraph", "Spanish syllables", "animals"), optional level, optional count. The lists are the standard published classroom lists served exactly as published (Dolch sight words and nouns, CVC families, digraph words, Spanish syllables, Turkish-English pairs). Use when you need a ready-to-use list of words for a lesson, worksheet, quiz, or flashcard set and do not already hold a dataset slug. Do not use when you need an interactive activity or tool metadata - use search_classroom_tools or get_classroom_tool instead. Behavior: read-only, idempotent, no authentication; returns the first count items in canonical order when count is given, otherwise the full filtered list, identical on every repeat, with a SHA-256 content_hash of the full dataset. An unknown topic or a level foreign to the matched dataset returns error -32602 with no partial results.
| Name | Type | Req | Description |
|---|---|---|---|
| count | integer | – | Optional maximum number of items to return, taken from the start of the canonical order; omit to return the full filtered list |
| level | string | – | Optional level or family within the matched dataset, same values as get_curriculum_dataset level_or_family (Dolch levels pre-primer, primer, grade-1, grade-2, grade-3; CVC rimes such as -at; digraphs… |
| topic | string | yes | Plain topic phrase, for example sight words, Dolch nouns, CVC, digraph, Spanish syllables, animals, colors, objects, Turkish early words; an exact dataset slug is also accepted |
| Name | Type | Req | Description |
|---|---|---|---|
| content_hash | string | – | SHA-256 of the full unfiltered dataset; changes only when the data changes |
| creator | string | yes | Dataset creator, always Birkan Yavuz |
| dataset_id | string | yes | Stable dataset id in the form birkanyavuz:<name>:v1 |
| invocation_id | string | yes | Unique receipt id for this call |
| item_count | integer | yes | Number of items in this response after count limiting |
| items | array | yes | The returned items in canonical order; element shape depends on the dataset (see get_curriculum_dataset) |
| record_digest | string | – | One-line citation naming the dataset, creator and endpoint |
| resource_uri | string | – | Stable edu:// URI for this dataset |
| total_count | integer | yes | Number of items in the filtered list before count limiting |
No examples provided.
list_classroom_tools List All K-12 Classroom Tools ~85
List all 24 interactive classroom tools in Birkan Yavuz's catalog. Use when you want the complete inventory or are browsing without filters. Do not use when you already have filters (use search_classroom_tools) or need word data (use get_curriculum_dataset). Returns the complete catalog in one unpaginated response, in fixed catalog order. Requires no authentication.
Input schema present but exposes no named parameters.
