Claude Code
claude mcp add --transport http lingard-vocab https://lingard.app/mcpCapabilities
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.
DiscoveredAdds 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.
DiscoveredAttaches 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.
DiscoveredCommits 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.
DiscoveredCreates 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.
DiscoveredFills 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.
DiscoveredReturns 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.
DiscoveredReturns 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.
DiscoveredLists, 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.
DiscoveredReturns 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.
DiscoveredReturns live Lingard profile level, topic, collection context, and the words the user already has: the context for suggesting level-appropriate new cards that are not duplicates.
DiscoveredPreviews 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.
DiscoveredPuts 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.
DiscoveredRewrites 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.
DiscoveredSearches the user's live Lingard account: vocabulary, learning context, English profile, totals, collection titles, saved words, flashcards, and missing vocabulary fields. Results are read from Firestore at the time of the call.
