Claude Code: deny. ### `lingard_attach_card_images` - The name "lingard_attach_card_images" says "attach": a word for a change. - The server marks it destructive (destructiveHint: true). - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Attaches generated or supplied images to existing Lingard cards. This tool does not generate images from prompt alone: pass actual imageBase64, dataUri, or imageUrl. 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. An imageUrl is downloaded from that address. Pass commit=true to write. ``` ### `lingard_commit_vocab_changes` - The name "lingard_commit_vocab_changes" says "commit": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Commits a previously previewed or freshly supplied Lingard vocabulary change. For AI-generated new cards, include all applicable useful fields except image by default: title, translate, pos, pron/ipa, syns, and examples with translations. For German/Romance nouns, include the dictionary article in title/word when needed, e.g. der Hund, die Reise, das Haus. Example text and example translation must highlight the target word/translated word with {}. form is not part of speech; use it only for the current inflected-form category, otherwise omit/null it. Do not write word+translation-only cards unless allowIncompleteCards=true was explicitly requested by the user. 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, so the user is asked to approve it. To only add new cards or fill empty fields, use lingard_add_words_to_collection or lingard_fill_missing_card_fields. ``` ### `lingard_update_example_translations` - The name "lingard_update_example_translations" says "update": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text 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. Use this when the user wants to change, add, or remove example translations — including leaving them empty, which is a supported card state, not an error. Read the current examples first with lingard_get_vocab_collection includeExamples:true, then send one `translations` entry per example, in order. Pass commit=true to write; without it the call returns the resulting examples as a preview. ``` ## Changes things (5) Creates or changes something that can be changed back. Claude Code: ask. ### `lingard_add_words_to_collection` - The name "lingard_add_words_to_collection" says "add": a word for a change. Description, as the server wrote it: ```untrusted-server-text Adds cards to an existing Lingard collection, deduplicating by normalized word title. Pass commit=true to write. Only collections with writable="full" accept new cards: curated Lingard collections are read-only and the unfiled bucket takes no new cards — create a collection with lingard_create_vocab_collection instead. By default every AI-generated card must include all applicable useful fields except image: title, translate, pos, pron/ipa, syns, and examples with translations. For German/Romance nouns, include the dictionary article in title/word when needed, e.g. der Hund, die Reise, das Haus. Example text and example translation must highlight the target word/translated word with {}. form is not part of speech; use it only for the current inflected-form category, otherwise omit/null it. Do not add word+translation-only cards unless the user explicitly requests sparse cards and allowIncompleteCards=true. 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 — use lingard_commit_vocab_changes for that. ``` ### `lingard_create_vocab_collection` - The name "lingard_create_vocab_collection" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text Creates a Lingard vocabulary collection, optionally with initial cards. Pass commit=true to write. By default every AI-generated card must include all applicable useful fields except image: title, translate, pos, pron/ipa, syns, and examples with translations. For German/Romance nouns, include the dictionary article in title/word when needed, e.g. der Hund, die Reise, das Haus. Example text and example translation must highlight the target word/translated word with {}. form is not part of speech; use it only for the current inflected-form category, otherwise omit/null it. Do not create word+translation-only cards unless the user explicitly requests sparse cards and allowIncompleteCards=true. ``` ### `lingard_fill_missing_card_fields` - The name "lingard_fill_missing_card_fields" says "fill": a word for a change. Description, as the server wrote it: ```untrusted-server-text Fills empty fields on existing Lingard cards. It never overwrites or clears a field that already has a value; to correct one — e.g. clear an incorrect grammatical form with clearFields:["form"] — use lingard_commit_vocab_changes. 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. Pass commit=true to write. ``` ### `lingard_get_learning_context` - The name "lingard_get_learning_context" says "get": a word for reading. - The description's first verb is "call": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Findings: high model-directed-text, warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text Call this first whenever the user asks for their current Lingard learning context, English profile, vocabulary totals, saved collections, collection titles, card counts, or missing-field stats. Reads live Lingard Firestore data; do not answer from memory or generic Lingard history. 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). Never tell the user a collection is missing or that the account looks wrong just because they only recognise some of the titles. ``` ### `lingard_set_learning_pauses` - The name "lingard_set_learning_pauses" says "set": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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). Name collections by uuid or exact title and sources by bookKey or exact title, as lingard_get_learning_pauses returns 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. Pass commit=true to write; without it the call returns a preview of the changes and the resulting state. ``` ## Only reads (7) Looks things up and changes nothing. Claude Code: allow. ### `fetch` - The name "fetch" says "fetch": a word for reading. - Tag untrusted-input: The description's first sentence says "uri": it reads web pages, which anyone can write. The input takes a URL (input.uri), and the tool reads it: it reads web pages, which anyone can write. - Tag outbound: The input takes a URL (input.uri): a request to a URL can carry data to whoever runs it. - Claude Code: ask, because it is tagged outbound. Description, as the server wrote it: ```untrusted-server-text Use this after search, or when the user gives a Lingard resource URI such as lingard://learning-context/en. Fetches the full live Lingard JSON record from Firestore. ``` ### `lingard_get_collection_gaps` - The name "lingard_get_collection_gaps" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Returns live Lingard cards in a collection that are missing requested fields such as translation, POS, pronunciation, examples, or image. Use before filling missing fields. A curated Lingard collection always reports zero gaps: its words come from the Lingard catalog and are not the user's to fill. ``` ### `lingard_get_learning_pauses` - The name "lingard_get_learning_pauses" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. Use this when the user asks what is paused or which collections they are studying, and before lingard_set_learning_pauses to get exact uuids, bookKeys and titles. ``` ### `lingard_get_vocab_collection` - The name "lingard_get_vocab_collection" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. Use this when the user asks what words/cards are in a specific Lingard collection. Pass includeExamples:true to also read each card's example sentences and their translations — required before editing them. ``` ### `lingard_get_word_suggestion_context` - The name "lingard_get_word_suggestion_context" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Returns live Lingard profile level, topic, collection context, and existing words so the calling AI can suggest level-appropriate new cards without duplicates. ``` ### `lingard_preview_vocab_changes` - The name "lingard_preview_vocab_changes" says "preview": a word for reading. Description, as the server wrote it: ```untrusted-server-text Previews a Lingard vocabulary collection/card change without writing to Firestore. For AI-generated new cards, include all applicable useful fields except image by default: title, translate, pos, pron/ipa, syns, and examples with translations. For German/Romance nouns, include the dictionary article in title/word when needed, e.g. der Hund, die Reise, das Haus. Example text and example translation must highlight the target word/translated word with {}. form is not part of speech; use it only for the current inflected-form category, otherwise omit/null it. ``` ### `search` - The name "search" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Use this when the user asks about their Lingard vocabulary, learning context, English profile, totals, collection titles, saved words, flashcards, or missing vocabulary fields. Returns live Lingard Firestore results; do not use generic memory or personal context instead. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `vocab`: ```json { "permissions": { "allow": [ "mcp__vocab__search", "mcp__vocab__lingard_get_vocab_collection", "mcp__vocab__lingard_get_collection_gaps", "mcp__vocab__lingard_get_word_suggestion_context", "mcp__vocab__lingard_preview_vocab_changes", "mcp__vocab__lingard_get_learning_pauses" ], "ask": [ "mcp__vocab__fetch", "mcp__vocab__lingard_get_learning_context", "mcp__vocab__lingard_create_vocab_collection", "mcp__vocab__lingard_add_words_to_collection", "mcp__vocab__lingard_fill_missing_card_fields", "mcp__vocab__lingard_set_learning_pauses" ], "deny": [ "mcp__vocab__lingard_commit_vocab_changes", "mcp__vocab__lingard_update_example_translations", "mcp__vocab__lingard_attach_card_images" ] } } ``` Capability tags behind the rules (a read tagged outbound is asked about): - `mcp__vocab__fetch`: untrusted-input, outbound - `mcp__vocab__lingard_attach_card_images`: untrusted-input
