Implementation Reference
- src/tools/data.ts:90-115 (handler)Generic handler function used by registerSimple for data_list_variations: resolves auth, GET requests '/workers/getDeclinaisons.php' with shopId/apiKey/format, structures response with structData, logs, handles errors gracefully.async ({ format }: CommonArgs, ctx: Ctx) => { try { const { shopId, apiKey } = resolveAuth(undefined, ctx); const data = await get(path, { idboutique: shopId, key: apiKey, format }); process.stderr.write( `[caisse][tool:${toolName}] ok type=${Array.isArray(data) ? 'array' : typeof data}` + (Array.isArray(data) ? ` len=${data.length}` : '') + '\n' ); //Array.isArray(data) ? data.slice(0, 50) : data const funcResult = structData( data); process.stderr.write(`[caisse][RES] ${JSON.stringify(data)} \n`); process.stderr.write(`[caisse][RES] funcResult ${JSON.stringify(funcResult)} \n`); return funcResult; //return { content, structuredContent: isText ? undefined : data }; } catch (e) { process.stderr.write(`[caisse][tool:${toolName}][error]\n`); process.stderr.write(`[caisse][tool:${toolName}][error] ${(e as Error).message}\n`); // renvoyer un message "propre" plutôt que laisser l’exception devenir un 424 return { content: [{ type: 'text', text: `Erreur pendant la préparation de la réponse: ${(e as Error).message}` }], is_error: true, }; } }
- src/tools/data.ts:11-13 (schema)Input schema for data_list_variations tool: optional 'format' parameter defaulting to 'json', enum of 'json', 'csv', 'html' for output format.const CommonShape = { format: z.enum(['json', 'csv', 'html']).default('json'), } satisfies Record<string, ZodTypeAny>;
- src/tools/data.ts:126-126 (registration)Specific registration of 'data_list_variations' tool using the registerSimple helper, linking to PHP endpoint '/workers/getDeclinaisons.php' and i18n titles/descriptions.registerSimple(server, 'data_list_variations', '/workers/getDeclinaisons.php', t('tools.data_list_variations.description'), t('tools.data_list_variations.title'));
- src/tools/data.ts:52-73 (helper)Helper function to structure tool responses: creates preview text content and structuredContent, truncates large arrays/strings for safe MCP response.function structData(data: any) { // on ne touche PAS à structuredContent (c’est ce que ChatGPT utilise) const light = Array.isArray(data) ? data.slice(0, 5000)//.map(({ id, nom, email, tel, ...r }) => ({ id, nom, email, tel })) : data; const maxLength = 40000; const preview = typeof light === 'string' ? (light.length > maxLength ? light.slice(0, maxLength) + '…(truncated)' : light) : safeStringify(light, 2, maxLength); // <-- aperçu court et “safe” const wrapped = Array.isArray(data) ? { data: data } : data && typeof data === 'object' ? data : { data: data }; return { content: [{ type: 'text', text: preview }], structuredContent: wrapped, }; }
- src/tools/data.ts:75-117 (helper)Helper function that registers simple data-listing tools like data_list_variations with common schema, read-only annotation, and generic HTTP-fetching handler.function registerSimple( server: McpServer | any, toolName: string, path: string, title: string, entityLabel: string ) { server.registerTool( toolName, { title, description: `Liste des ${entityLabel}`, inputSchema: CommonShape, // ZodRawShape, annotations: { readOnlyHint: true } }, async ({ format }: CommonArgs, ctx: Ctx) => { try { const { shopId, apiKey } = resolveAuth(undefined, ctx); const data = await get(path, { idboutique: shopId, key: apiKey, format }); process.stderr.write( `[caisse][tool:${toolName}] ok type=${Array.isArray(data) ? 'array' : typeof data}` + (Array.isArray(data) ? ` len=${data.length}` : '') + '\n' ); //Array.isArray(data) ? data.slice(0, 50) : data const funcResult = structData( data); process.stderr.write(`[caisse][RES] ${JSON.stringify(data)} \n`); process.stderr.write(`[caisse][RES] funcResult ${JSON.stringify(funcResult)} \n`); return funcResult; //return { content, structuredContent: isText ? undefined : data }; } catch (e) { process.stderr.write(`[caisse][tool:${toolName}][error]\n`); process.stderr.write(`[caisse][tool:${toolName}][error] ${(e as Error).message}\n`); // renvoyer un message "propre" plutôt que laisser l’exception devenir un 424 return { content: [{ type: 'text', text: `Erreur pendant la préparation de la réponse: ${(e as Error).message}` }], is_error: true, }; } } ); }
