## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

First indexed and scored.

## MCP tools (6)

### `semantic_search` (~126 tokens)

Recherche sémantique dans la documentation MO5 (base de connaissances). Si aucun résultat n'est trouvé avec le score demandé, une seconde tentative est effectuée automatiquement avec un seuil plus permissif.

Input parameters:

- `maxResults` (number)
- `minSimilarityScore` (number): Score minimum de similarité (0.0 à 1.0). Un fallback automatique à 0.5 est appliqué si aucun résultat n'est trouvé.
- `query` (string, required): La question ou les mots-clés de recherche
- `tags` (array): Filtres par thématiques

### `get_chunk_context` (~138 tokens)

Récupère le contexte élargi autour d'un chunk retourné par semantic_search : les chunks voisins (avant/après) dans le même document. Utile quand une explication technique est découpée sur plusieurs chunks et que la réponse semble incomplète ou tronquée.

Input parameters:

- `chunkIndex` (number, required): L'index du chunk central (champ position.chunkIndex dans les résultats de semantic_search)
- `contextSize` (number): Nombre de chunks à récupérer de chaque côté (défaut: 2)
- `documentId` (string, required): L'ID du document (champ document.documentId dans les résultats de semantic_search)

### `list_official_docs` (~85 tokens)

Liste les documents officiels et de développement Thomson MO5 (manuels, guides techniques). Utile pour identifier quelles ressources existent avant de faire une recherche sémantique ciblée, ou pour fournir un lien de téléchargement direct à l'utilisateur.

Input parameters:

- `tag` (string): Filtrer par tag (ex: 'basic', 'assembleur', 'hardware'). Optionnel.

### `make_fd` (~127 tokens)

Génère une image disquette .fd bootable pour Thomson MO5 à partir d'un ou plusieurs binaires compilés avec CMOC. Le boot loader MO5 est embarqué directement dans le script — aucune dépendance externe requise. Équivalent de : fdfs -addBL output.fd BOOTMO.BIN program.BIN

Input parameters:

- `input_bins` (array, required): Liste des chemins vers les fichiers .BIN compilés avec CMOC (avec header Thomson)
- `output_fd` (string, required): Chemin de sortie de l'image disquette, ex: output/MYAPP.fd

### `fd_to_sd` (~116 tokens)

Convertit une image disquette .fd (format 3.5" 720 Ko) en .sd (format 5.25" 320 Ko) pour une utilisation avec SDDrive — le composant qui simule un lecteur de disquette sur Thomson MO5 via carte SD.

Input parameters:

- `input_fd` (string, required): Chemin vers le fichier .fd source, ex: output/MYAPP.fd
- `output_sd` (string, required): Chemin de sortie du fichier .sd, ex: output/MYAPP.sd

### `png_to_mo5_sprite` (~123 tokens)

Convertit une image PNG en tableaux C (FORME + COULEUR) pour le Thomson MO5. Génère un fichier .h directement utilisable avec le SDK MO5 (mo5_sprite.h). Format : 1 octet = 8 pixels, 2 couleurs par groupe de 8 pixels.

Input parameters:

- `image_path` (string, required): Chemin vers le fichier PNG source, ex: assets/hero.png
- `output_path` (string, required): Chemin de sortie du fichier .h généré, ex: include/assets/hero.h
