Implementation Reference

  • The main handler function for the zset_add MCP tool. Ensures Redis connection and calls the underlying RedisService.zadd method, returning the result as MCP content.
    private async handleZsetAdd(args: any) { this.ensureRedisConnection(); const result = await this.redisService!.zadd(args.key, args.members); return { content: [ { type: 'text', text: JSON.stringify(result, null, 2) } ] }; }
  • Input schema definition for the zset_add tool, specifying key (string) and members (single object {member: string, score: number} or array thereof).
    inputSchema: { type: 'object', properties: { key: { type: 'string', description: '有序集合键名' }, members: { oneOf: [ { type: 'object', properties: { member: { type: 'string', description: '成员' }, score: { type: 'number', description: '分数' } }, required: ['member', 'score'], description: '单个成员' }, { type: 'array', items: { type: 'object', properties: { member: { type: 'string', description: '成员' }, score: { type: 'number', description: '分数' } }, required: ['member', 'score'] }, description: '成员数组' } ], description: '要添加的成员或成员数组' } }, required: ['key', 'members']
  • Registration in the tool dispatcher switch statement within CallToolRequestHandler, routing calls to the zset_add handler.
    case 'zset_add': return await this.handleZsetAdd(args);
  • Helper method in RedisService that implements the ZADD Redis command, converting MCP parameters to redis client zAdd format and handling single/array inputs.
    async zadd(key: string, members: RedisSortedSetMember | RedisSortedSetMember[]): Promise<RedisOperationResult<number>> { return this.executeCommand(async () => { if (!this.client) throw new Error('Redis client not initialized'); if (Array.isArray(members)) { const args: Array<{ score: number, value: string }> = members.map(m => ({ score: m.score, value: m.member })); return await this.client.zAdd(key, args); } else { return await this.client.zAdd(key, { score: members.score, value: members.member }); } }); }
