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 Security97
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token. View diagnostics → Pass
- 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 Usability76
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 3014 tokens (~137/item across 22 items; 15 tools + 7 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 Management20
- Stability observed for 6 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage83
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 42% 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 15 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 16 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 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 →
fetch Fetch Lingard Vocab Record ~173
Fetches the full live Lingard JSON record for a search-result id (e.g. "learning-context:en") or a Lingard resource URI such as lingard://learning-context/en.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | – | Preferred selector: a search-result id, e.g. "learning-context:en". Takes `id` OR `uri` (not both); if both are given, `id` wins. |
| targetLang | string | – | Fallback used only when neither `id` nor `uri` is provided: a language code (en, de, es, fr, it, pl, pt) whose learning context to fetch. |
| uri | string | – | Alternative selector, used only when `id` is omitted: a Lingard resource URI, e.g. "lingard://learning-context/en". |

lingard_add_words_to_collection Add Lingard Words To Collection ~348
Adds cards to an existing Lingard collection, deduplicating by normalized word title; commit=true writes them. Only collections with writable="full" accept new cards: curated Lingard collections are read-only and the unfiled bucket takes no new cards. Unless allowIncompleteCards is true, a new card needs title, translate, pos, pron/ipa, syns, and examples with translations; image is optional. A German or Romance noun title carries its dictionary article when one is used, e.g. der Hund, die Reise, das Haus. In example text and example translation the target word and the translated word are marked with {}. form is not part of speech: it holds the inflected-form category of the current word and stays empty for base forms. It only adds: a word already in the collection gets its empty fields filled (mergeMode "fill_missing", the default) or is left alone ("add_only"); a value that is already filled in is never changed or cleared.
| Name | Type | Req | Description |
|---|---|---|---|

lingard_attach_card_images Attach Lingard Card Images ~178
Attaches supplied images to existing Lingard cards. It does not generate images: each entry carries the image itself as imageBase64 or dataUri, or an imageUrl that the server downloads. PNG, JPEG, WebP, and SVG inputs are converted to WebP and uploaded as private custom card images; an image the card already has is replaced. commit=true writes.
| Name | Type | Req | Description |
|---|---|---|---|
| collectionTitle | string | – | – |
| collectionUuid | string | – | – |
| commit | boolean | – | True uploads and attaches. Default false returns a dry-run preview without writing. |
| images | array | yes | One entry per card to illustrate. Each entry needs a card selector (`cardId` or `title`) and exactly one image source (`imageBase64`, `dataUri`, or `imageUrl`). |

lingard_commit_vocab_changes Commit Lingard Vocabulary Changes ~187
Commits a previously previewed or freshly supplied Lingard vocabulary change. Unless allowIncompleteCards is true, a new card needs title, translate, pos, pron/ipa, syns, and examples with translations; image is optional. A German or Romance noun title carries its dictionary article when one is used, e.g. der Hund, die Reise, das Haus. In example text and example translation the target word and the translated word are marked with {}. form is not part of speech: it holds the inflected-form category of the current word and stays empty for base forms. This is the tool that corrects existing cards: mergeMode:"overwrite_non_empty" replaces values that are already filled in and clearFields:["form"] clears a wrong grammatical form, which is why it is marked destructive.

lingard_create_vocab_collection Create Lingard Vocabulary Collection ~245
Creates a Lingard vocabulary collection, optionally with initial cards; commit=true writes it. Unless allowIncompleteCards is true, a new card needs title, translate, pos, pron/ipa, syns, and examples with translations; image is optional. A German or Romance noun title carries its dictionary article when one is used, e.g. der Hund, die Reise, das Haus. In example text and example translation the target word and the translated word are marked with {}. form is not part of speech: it holds the inflected-form category of the current word and stays empty for base forms.

lingard_fill_missing_card_fields Fill Missing Lingard Card Fields ~113
Fills empty fields on existing Lingard cards. It never overwrites or clears a field that already has a value. Works on the user's own collections and on the "Words not in a collection" bucket; curated Lingard collections are read-only because their content comes from the Lingard catalog. commit=true writes.

lingard_get_collection_gaps Get Lingard Collection Gaps ~186
Returns live Lingard cards in a collection that are missing requested fields such as translation, POS, pronunciation, examples, or image. A curated Lingard collection always reports zero gaps: its words come from the Lingard catalog and are not the user's to fill.
| Name | Type | Req | Description |
|---|---|---|---|
| collectionTitle | string | – | Collection selector (alternative to `collectionUuid`): the collection title. |
| collectionUuid | string | – | Collection selector: its UUID. One of `collectionUuid` or `collectionTitle` is required (UUID wins if both are given). |

lingard_get_learning_context Get Lingard Learning Context ~192
Returns the user's current Lingard learning context, read live from their account: English profile, vocabulary totals, saved collections and their titles, card counts, and missing-field stats. Earlier answers in the conversation may be out of date; this is the account as it stands now. The list covers every collection the account has, so the per-collection counts add up to the card total (totals.truncated marks a library too large to list in full). Every collection reports `source`: "user" (made by the user), "catalog" (a curated Lingard collection — read-only, its words come from the Lingard catalog) and "unfiled" (the bucket of cards saved while reading, which belong to no collection). Catalog and unfiled entries carry titles the user did not choose; they belong to the same account all the same.

lingard_get_learning_pauses Get Lingard Learning Pauses ~122
Lists, for one language, the user's collections and sources (books, the news) and which of them are on pause. A collection or source on pause gives the automatic «Now learning» sessions no words — no new words and no reviews — and is not counted in the day's goals or reminders; opening it in the app still studies it as usual. Each entry carries the exact uuid, bookKey, and title that pause changes take.

lingard_get_vocab_collection Get Lingard Vocabulary Collection ~184
Returns live cards from one Lingard vocabulary collection by UUID or title, including curated Lingard collections and the "Words not in a collection" bucket of cards saved while reading. With includeExamples:true it also returns each card's example sentences and their translations, which editing examples starts from.
| Name | Type | Req | Description |
|---|---|---|---|
| collectionTitle | string | – | Collection selector (alternative to `collectionUuid`): the collection title. |
| collectionUuid | string | – | Collection selector (preferred): its UUID. One of `collectionUuid` or `collectionTitle` is required. |
| includeExamples | boolean | – | Default false. True returns the full example rows (`examples`: example text, translation line, enabled flag) for every card instead of just the `exampleCount`. |

lingard_preview_vocab_changes Preview Lingard Vocabulary Changes ~151
Previews a Lingard vocabulary collection/card change without writing to Firestore. Cards are checked as on commit. Unless allowIncompleteCards is true, a new card needs title, translate, pos, pron/ipa, syns, and examples with translations; image is optional. A German or Romance noun title carries its dictionary article when one is used, e.g. der Hund, die Reise, das Haus. In example text and example translation the target word and the translated word are marked with {}. form is not part of speech: it holds the inflected-form category of the current word and stays empty for base forms.

lingard_set_learning_pauses Set Lingard Learning Pauses ~253
Puts collections and sources on pause or takes them off it, for one language — e.g. "study only my Travel collection this week", "pause the news words", "resume everything". action: "pause" or "resume" the listed ones; "only" — resume the listed ones and pause every other collection and source of the language; "resume_all" — take every pause off (lists ignored). Collections are named by uuid or exact title and sources by bookKey or exact title, as the learning-pause list reports them. A paused item gives the automatic «Now learning» sessions no words and is not counted in goals or reminders; opening it in the app still studies it. commit=true writes; without it the call returns a preview of the changes and the resulting state.
| Name | Type | Req | Description |
|---|---|---|---|
| action | string | yes | – |
| collections | array | – | Collections by uuid or exact title. |
| commit | boolean | – | True writes. Default false returns a preview without writing. |

lingard_update_example_translations Update Lingard Example Translations ~221
Rewrites only the translation line of examples that already exist on Lingard cards; the example sentence, its {} highlights and its audio/typing markers are left exactly as they are. It changes, adds, or removes example translations; an empty translation is a supported card state, not an error. `translations` holds one entry per existing example, in order, so it is built from the card's current examples (a collection read with includeExamples:true lists them). commit=true writes; without it the call returns the resulting examples as a preview.
| Name | Type | Req | Description |
|---|---|---|---|
| cards | array | yes | One entry per card to edit. Each entry needs a card selector (`cardId`, or `title` plus a collection when the word occurs in several) and `translations`. |
| collectionTitle | string | – | Optional default collection title for cards addressed by title. |
| collectionUuid | string | – | Optional default collection for cards addressed by title. |

How do I install the Lingard Vocab MCP server?
Lingard Vocab is a hosted endpoint at https://lingard.app/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.
remote · lingard.app
claude mcp add --transport http app-lingard-vocab 'https://lingard.app/mcp'
What is the Lingard Vocab MCP server?
Lingard Vocab is an MCP server listed in the public MCP registry as app.lingard/vocab. Build and enrich your Lingard vocabulary: topic collections, flashcards, translations, examples. This page covers its hosted endpoint (https://lingard.app/mcp).
Is the Lingard Vocab MCP server safe to use?
Lingard Vocab scores 82 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Lingard Vocab MCP server expose?
Lingard Vocab exposes 15 tools: search, fetch, lingard_get_learning_context, lingard_get_vocab_collection, lingard_get_collection_gaps, and 10 more. Their descriptions and schemas cost roughly 2,776 tokens of context every time the server is loaded.
Does the Lingard Vocab MCP server require authentication?
Yes. Lingard Vocab asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.
Is the Lingard Vocab MCP server still maintained?
Lingard Vocab is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
