Redis MCP

Instructions

Implementation Reference

• src/services/mcpService.ts:1194-1206 (handler)

  MCP tool handler for 'key_delete' that ensures Redis connection, calls RedisService.del with the provided keys, and formats the result as MCP response content.

  private async handleKeyDelete(args: any) {
    this.ensureRedisConnection();
    const result = await this.redisService!.del(args.keys);
    
    return {
      content: [
        {
          type: 'text',
          text: JSON.stringify(result, null, 2)
        }
      ]
    };
  }

• src/services/mcpService.ts:483-501 (schema)

  Input schema definition for the 'key_delete' tool, specifying keys as string or array of strings.

  name: 'key_delete',
  description: '删除键',
  inputSchema: {
    type: 'object',
    properties: {
      keys: {
        oneOf: [
          { type: 'string', description: '键名' },
          { 
            type: 'array', 
            items: { type: 'string' },
            description: '键名数组'
          }
        ],
        description: '要删除的键名或键名数组'
      }
    },
    required: ['keys']
  }

• src/services/mcpService.ts:686-687 (registration)

  Registration of the 'key_delete' tool handler in the CallToolRequestSchema switch statement.

  case 'key_delete':
    return await this.handleKeyDelete(args);

• src/services/redisService.ts:143-153 (helper)

  Supporting method in RedisService that wraps the Redis client's DEL command to delete single or multiple keys.

  async del(key: string | string[]): Promise<RedisOperationResult<number>> {
    return this.executeCommand(async () => {
      if (!this.client) throw new Error('Redis client not initialized');
      
      if (Array.isArray(key)) {
        return await this.client.del(key);
      } else {
        return await this.client.del(key);
      }
    });
  }
