- src/services/mcpService.ts:990-1002 (handler)The main handler function for the 'hash_del' tool. It ensures Redis connection, calls hdel on RedisService with key and fields, and returns the result as MCP content.private async handleHashDel(args: any) { this.ensureRedisConnection(); const result = await this.redisService!.hdel(args.key, args.fields); return { content: [ { type: 'text', text: JSON.stringify(result, null, 2) } ] }; }
- src/services/mcpService.ts:247-268 (registration)Registration of the 'hash_del' tool in the ListTools response, defining name, description, and input schema.{ name: 'hash_del', description: '删除哈希字段', inputSchema: { type: 'object', properties: { key: { type: 'string', description: '哈希键名' }, fields: { oneOf: [ { type: 'string', description: '字段名' }, { type: 'array', items: { type: 'string' }, description: '字段名数组' } ], description: '要删除的字段名或字段名数组' } }, required: ['key', 'fields'] } },
- src/services/mcpService.ts:654-655 (handler)Dispatch case in the main CallToolRequest handler that routes 'hash_del' calls to the specific handleHashDel method.case 'hash_del': return await this.handleHashDel(args);
